65\times 240+x\times 150=21000
Multiply both sides of the equation by 100.
15600+x\times 150=21000
Multiply 65 and 240 to get 15600.
x\times 150=21000-15600
Subtract 15600 from both sides.
x\times 150=5400
Subtract 15600 from 21000 to get 5400.
x=\frac{5400}{150}
Divide both sides by 150.
x=36
Divide 5400 by 150 to get 36.
