x+5-3=4x-7
Combine 3x and -2x to get x.
x+2=4x-7
Subtract 3 from 5 to get 2.
x+2-4x=-7
Subtract 4x from both sides.
-3x+2=-7
Combine x and -4x to get -3x.
-3x=-7-2
Subtract 2 from both sides.
-3x=-9
Subtract 2 from -7 to get -9.
x=\frac{-9}{-3}
Divide both sides by -3.
x=3
Divide -9 by -3 to get 3.
