450=320+x\times 60
Multiply 8 and 40 to get 320.
320+x\times 60=450
Swap sides so that all variable terms are on the left hand side.
x\times 60=450-320
Subtract 320 from both sides.
x\times 60=130
Subtract 320 from 450 to get 130.
x=\frac{130}{60}
Divide both sides by 60.
x=\frac{13}{6}
Reduce the fraction \frac{130}{60} to lowest terms by extracting and canceling out 10.
