180x+120-200x=120
Subtract 200x from both sides.
-20x+120=120
Combine 180x and -200x to get -20x.
-20x=120-120
Subtract 120 from both sides.
-20x=0
Subtract 120 from 120 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -20 is not equal to 0, x must be equal to 0.
