80x+20000-100x=17900
Use the distributive property to multiply 100 by 200-x.
-20x+20000=17900
Combine 80x and -100x to get -20x.
-20x=17900-20000
Subtract 20000 from both sides.
-20x=-2100
Subtract 20000 from 17900 to get -2100.
x=\frac{-2100}{-20}
Divide both sides by -20.
x=105
Divide -2100 by -20 to get 105.
