12x-6<14x-2
Use the distributive property to multiply 3 by 4x-2.
12x-6-14x<-2
Subtract 14x from both sides.
-2x-6<-2
Combine 12x and -14x to get -2x.
-2x<-2+6
Add 6 to both sides.
-2x<4
Add -2 and 6 to get 4.
x>\frac{4}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x>-2
Divide 4 by -2 to get -2.
