2x+192-2.4x=180
Use the distributive property to multiply 2.4 by 80-x.
-0.4x+192=180
Combine 2x and -2.4x to get -0.4x.
-0.4x=180-192
Subtract 192 from both sides.
-0.4x=-12
Subtract 192 from 180 to get -12.
x=\frac{-12}{-0.4}
Divide both sides by -0.4.
x=\frac{-120}{-4}
Expand \frac{-12}{-0.4} by multiplying both numerator and the denominator by 10.
x=30
Divide -120 by -4 to get 30.
