\frac{30}{2}=x+6+x+2
Divide both sides by 2.
15=x+6+x+2
Divide 30 by 2 to get 15.
15=2x+6+2
Combine x and x to get 2x.
15=2x+8
Add 6 and 2 to get 8.
2x+8=15
Swap sides so that all variable terms are on the left hand side.
2x=15-8
Subtract 8 from both sides.
2x=7
Subtract 8 from 15 to get 7.
x=\frac{7}{2}
Divide both sides by 2.
