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