60x+1800-45x=2140
Use the distributive property to multiply 45 by 40-x.
15x+1800=2140
Combine 60x and -45x to get 15x.
15x=2140-1800
Subtract 1800 from both sides.
15x=340
Subtract 1800 from 2140 to get 340.
x=\frac{340}{15}
Divide both sides by 15.
x=\frac{68}{3}
Reduce the fraction \frac{340}{15} to lowest terms by extracting and canceling out 5.
