If you're solving for x, then simplify both sides of the inequality, then isolating the variable. 
x < 3
You solve it by using order of operations, aka PEMDAS (if you learned that). So you would bring 4x to the other side by subtracting it by itself and moving it to the other side. 2x >4x-6
                           -4x  -4x
                          --------------
                          -2x > -6.

Then you divide -2 by both sides.

                         -2x>-6
                         ----  ----
                          -2   -2
                          
                           x>3
