1200x+18000-1800x=14400
Use the distributive property to multiply 1800 by 10-x.
-600x+18000=14400
Combine 1200x and -1800x to get -600x.
-600x=14400-18000
Subtract 18000 from both sides.
-600x=-3600
Subtract 18000 from 14400 to get -3600.
x=\frac{-3600}{-600}
Divide both sides by -600.
x=6
Divide -3600 by -600 to get 6.
