-2x+4<-20
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-2x<-20-4
Subtract 4 from both sides.
-2x<-24
Subtract 4 from -20 to get -24.
x>\frac{-24}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x>12
Divide -24 by -2 to get 12.
