5x=-5

divide by 5 both sides of an equation.

5x/5=-5/5

How do I find x if 37-91+3x=42

Answers

add 91 to the other side to cancel it out-
37-91+3x=42
    +91      +91
____________
37+3x=133

subtract 37 from the other side to cancel it out
37+3x=133
-37       -37
_________
3x=96

then divide 96 by 3 to get x by itself
3x=96
3     3

once you get x alone it should equal 32
x=32
