x+22-2.1x=0
Subtract 2.1x from both sides.
-1.1x+22=0
Combine x and -2.1x to get -1.1x.
-1.1x=-22
Subtract 22 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-22}{-1.1}
Divide both sides by -1.1.
x=\frac{-220}{-11}
Expand \frac{-22}{-1.1} by multiplying both numerator and the denominator by 10.
x=20
Divide -220 by -11 to get 20.
