1200\times 2=\left(20+60\right)x
Multiply both sides by 2.
2400=\left(20+60\right)x
Multiply 1200 and 2 to get 2400.
2400=80x
Add 20 and 60 to get 80.
80x=2400
Swap sides so that all variable terms are on the left hand side.
x=\frac{2400}{80}
Divide both sides by 80.
x=30
Divide 2400 by 80 to get 30.
