4x+3+x=7x-13
Subtract 2 from 5 to get 3.
5x+3=7x-13
Combine 4x and x to get 5x.
5x+3-7x=-13
Subtract 7x from both sides.
-2x+3=-13
Combine 5x and -7x to get -2x.
-2x=-13-3
Subtract 3 from both sides.
-2x=-16
Subtract 3 from -13 to get -16.
x=\frac{-16}{-2}
Divide both sides by -2.
x=8
Divide -16 by -2 to get 8.
