42000+2000x-6000x=30000
Subtract 6000x from both sides.
42000-4000x=30000
Combine 2000x and -6000x to get -4000x.
-4000x=30000-42000
Subtract 42000 from both sides.
-4000x=-12000
Subtract 42000 from 30000 to get -12000.
x=\frac{-12000}{-4000}
Divide both sides by -4000.
x=3
Divide -12000 by -4000 to get 3.
