so u want to find x in ur question given,8x-(3x+10)=34getting x terms to a side and numbers to one side8x-3x=34-105x=24x=24/5x=4.8or u can do it as adding -10 on both sides8x-3x+10-10=34-105x=24divide with 5 on both sides5x/5=24/5x=24/5x=4.8

The - in front the brackets affect every term inside:8x-3x-10=34Now you can proceed as usual, add 10 in each side to isolate the terms with x8x-3x=34+105x=44Divide by 5 on each sideX=44/5X=8.8

The - gets multiplied inside so it becomes 8x-3x-10=34.now taking x terms 5x-10=34...taking all the numerical to one side....5x=34+10.....5x=44.....to find the value of x...the 5 should be taken to other side where it gets divided....x=44/5

1. multiply out the brackets 8x - 3x-10 =342. gather the x values 5x - 10 = 343. gather the whole numbers on oneside and x values on the other side 5x = 34+104. so therefore 5x =445. x= 44/5 OR x= 8.8

Exam tip: you can check the answer by substituting your 'x' value back into the equation to achieve a value of "34". This is useful in exams to do a quick check!

If 8x -(3x + 10) = 34Step 1: Collect like terms: 8x - (3x + 10) = 5x - 10Step 2: 5x - 10 = 34Step 3: Add 10 to both sides. 5x = 44Step 4: Divide both sides by 5 so x = 44/5 = 8.8

Remember: Always deal with brackets first.When there is a negative just outside the brackets, it is the same as it being negative 1. So:8x -1(3x+10) = 34To get rid of the brackets, multiply -1 x 3 and -1 by 10. That gives:8x - 3x - 10 = 34Get the x's on one side and the numbers on the other. The x's are already conveniently on the same side. However, you need to move the 10 to the right side, so change the sign from negative to positive:8x - 3x = 34 + 10Subtract on left and add on right:5x = 44You want x alone, without the 5. 5x just means 5 times x. To get rid of multiplication, you need to divide. Divide both sides by 5. 5x ÷ 5 = 44 ÷ 5That will erase the 5 from the left side. On the right side, another way to write 44 ÷ 5 is as the fraction 44 over 5. They mean the same thing. So:x = 44/5That is the fraction 44 over 5. Can we simplify it? Not really, since you can't divide an even number like 44 by 5. So, the answer you have is complete. P.S. You only need to write it as a decimal if the question asks you to (for example, to give your answer to 1 decimal point).

Hi there donalana!Algebraic questions at your stage can be simplified if one remembers BMDAS!I like to remember it as Bad Moms Dont Act Silly!The initials of this mnemonic rule give you the operations and their order in which to execute them. This means the order of operations is:Brackets, multiply, divide, add, substract.Remember the order of them with BMDASKnowing this we can breeze through the problem as followsBracketsMultiply out the negative sign outside the bracket and you will get:8x-3x-10=34remember to multiply all the terms inside the bracket by -1! This includes the term '10'. 2. MultiplyAll the terms are multiplied!3. DivideThere is nothing to divide at this stage!4. AddNothing to do here!5. Substract8x-3x =5xTherefore we are left with 5x -10 = 34Let's pass the '-10' term to the other side by adding ten to the RHS5x = 44Divide by 5 both sides and we get...x=44/5 OR x=8.8I hope this helped! :)

The minus symbol applies to everything inside of the brackets so to make the equation look easier to simplify:8x - 3x -+ 10 = 34;+- = -;8x -3x -10 =34;5x - 10 = 34;(+10) 5x - 10 = 34 (+10)5x = 44:(/5) 5x = 44 (/5)x= 44/5 You can do whatever you want when you apply functions (e.g. squaring or timesing by a number) to both sides. In this case I added 10 to both side to get the 5x on its own. Then to get x on its own, I then divided both sides by the 5.

8x - (3x+10)=34=> 8x -3x -10 = 34=> 5x = 44=> x= 44/5

Hello donalana, 8x-(3x+10)=34For the problem above, you BODMAS as we collect the like terms.We start off by opening up the brackets.8x-3x-10=34collecting like terms8x-3x=34+10Simplifying each side5x =44x=44/5 = 8.8

Hi donalanaIn the above problem we use BODMAS to work it out. Now let's get started by writing the equestion. 8x-(3x+10)=34Now we start by opening the brackets -(3x+10)-3x-10 ... the sign change because we multiple the numbers in the bracket by - 1Now we combine the math again 8x-3x -10 =34We but like terms together fast before going into the next step of BODMAS 8x-3x =34+10....now - 10 has changed the sign because we closed it to the other side of the equal sigh and became +108x-3x =5x34+10=445x=44....we divide both sides by 5 to get the value of x5x/5=44/5x=8.8There you got it as simple as that!

8x-(3x+10)=341) 8x -3x-10=34 ( we multiplied the minus with every term inside the bracket)2) 8x-3x =10+34 ( we separated the terms ) 3) 5x=24 ( we did the adding and substraction of the terms) 4) x=24 /5 ( we divided with X coeficient )so X= 24/5
