9y=117
y=117/9=13
x/4=9
x=9 x 4=36
b-43=51
b=51+43=94

1) Divide both sides by 9 to get y = 13.
2) Multiply both sides by 4 to get x = 36.
3) Add 43 to both sides to get b = 94.
These problems all work on the principle that if an equation, say a = b, is true, you can do the same thing to both sides and it will still be true. So a + c = b + c is true, and a/c = b/c, and ac = bc, and so on.
