4800=60\times 80+\left(60-30\right)x
Multiply 60 and 80 to get 4800.
4800=4800+\left(60-30\right)x
Multiply 60 and 80 to get 4800.
4800=4800+30x
Subtract 30 from 60 to get 30.
4800+30x=4800
Swap sides so that all variable terms are on the left hand side.
30x=4800-4800
Subtract 4800 from both sides.
30x=0
Subtract 4800 from 4800 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 30 is not equal to 0, x must be equal to 0.
