4\times 80\left(2.5-x\right)+3\times 60x=480
Multiply both sides of the equation by 240, the least common multiple of 60,80.
320\left(2.5-x\right)+3\times 60x=480
Multiply 4 and 80 to get 320.
800-320x+3\times 60x=480
Use the distributive property to multiply 320 by 2.5-x.
800-320x+180x=480
Multiply 3 and 60 to get 180.
800-140x=480
Combine -320x and 180x to get -140x.
-140x=480-800
Subtract 800 from both sides.
-140x=-320
Subtract 800 from 480 to get -320.
x=\frac{-320}{-140}
Divide both sides by -140.
x=\frac{16}{7}
Reduce the fraction \frac{-320}{-140} to lowest terms by extracting and canceling out -20.
