Inverse
dont get what inverse is or how to work out the mising numbers.
my homework says 37+x=69 and x/4=8
Answers
you have to subtract 37 to get the x by itself, and then you have to do the same thing to the other side of the equation. so:
37 + x = 69
-37 -37
x = 32
x/4 = 8
this time you have to multiply by 4 to get the x by itself. but then you have to do the same thing to the other side
4(x/4) = 8(4)
x = 32

that didn't come out the way i typed it: 37 + x - 37 = 69 - 37 (subtract 37 from both sides), leaving: x = 32
