6-3x<x+18
Use the distributive property to multiply 3 by 2-x.
6-3x-x<18
Subtract x from both sides.
6-4x<18
Combine -3x and -x to get -4x.
-4x<18-6
Subtract 6 from both sides.
-4x<12
Subtract 6 from 18 to get 12.
x>\frac{12}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x>-3
Divide 12 by -4 to get -3.
