The first thing you have to do is group together like terms, and remember that since this is an equation, what you do to one side you have to do to the other side. I'll show you this in steps.
4x + 2x = 9x - 6 Group together like-terms on the left hand side to get
6x = 9x - 6 Subtract 9x from both sides to get
6x - 9x = -6 (at this point, note that the 9x on the right hand side disappeared. This should happen, since subtract 9x would make 9x on the right hand side equal to zero).
Now, group together like terms on the left hand side, to get
-3x = -6
Since our goal is to isolate x, we divide both sides by -3
-3x/-3 = -6/-3
x = 2

4x+2x=9x-6
=> 6x=9x-6
=> 9x-6x=6
=> 3x=6
=> x=2
hence x=2

4x+2x=6x,you need to get x by itself so subtract 9x from both sides. -3x= -6 now divide by -3 the answer is 2

4x+2x=9x-6 subtract 9x from each side.
-3x=-6 divide by -3
x=2

4x + 2x = 9x - 6
6x = 9x - 6 add 4x and 2x together
-3x = -6 subbtract 9x to both side, 6x - 9x = -3x
x = 2 divide both side by -2
x is 2

add 4x+2x together = 6X
then subtract the 9x to the other side and get -3x=-6
x=2

4x + 2x = 9x -6
6x - 9x = -6
-3x = -6
3x = 6
x = 6/3
x = 2

6X=9X-6 (add the 2X and 4X)
-3X=-6 (subtract 9X from both sides)
3X=6 (multiply both sides by -1)
X=2 (devide both sides by 3)
