72=2x+8+2x
Use the distributive property to multiply 2 by x+4.
72=4x+8
Combine 2x and 2x to get 4x.
4x+8=72
Swap sides so that all variable terms are on the left hand side.
4x=72-8
Subtract 8 from both sides.
4x=64
Subtract 8 from 72 to get 64.
x=\frac{64}{4}
Divide both sides by 4.
x=16
Divide 64 by 4 to get 16.
