12x+40\left(x+10\right)=2480
Multiply 20 and 2 to get 40.
12x+40x+400=2480
Use the distributive property to multiply 40 by x+10.
52x+400=2480
Combine 12x and 40x to get 52x.
52x=2480-400
Subtract 400 from both sides.
52x=2080
Subtract 400 from 2480 to get 2080.
x=\frac{2080}{52}
Divide both sides by 52.
x=40
Divide 2080 by 52 to get 40.
