180-5.5x=110
Combine -6x and 0.5x to get -5.5x.
-5.5x=110-180
Subtract 180 from both sides.
-5.5x=-70
Subtract 180 from 110 to get -70.
x=\frac{-70}{-5.5}
Divide both sides by -5.5.
x=\frac{-700}{-55}
Expand \frac{-70}{-5.5} by multiplying both numerator and the denominator by 10.
x=\frac{140}{11}
Reduce the fraction \frac{-700}{-55} to lowest terms by extracting and canceling out -5.
