20180-2018x-2017x=4040
Use the distributive property to multiply 2018 by 10-x.
20180-4035x=4040
Combine -2018x and -2017x to get -4035x.
-4035x=4040-20180
Subtract 20180 from both sides.
-4035x=-16140
Subtract 20180 from 4040 to get -16140.
x=\frac{-16140}{-4035}
Divide both sides by -4035.
x=4
Divide -16140 by -4035 to get 4.
