#x = 4#

Explanation:

To solve for the variable #x#, we have to isolate it (make it by itself). To do so, first add #color)(blue)6# to both sides of the equation:
#3x - 6 quadcolor(blue)(+quad6) = 6 quadcolor(blue)(+quad6)#

#3x = 12#

Now divide both sides by #color(blue)3#:
#(3x)/color(blue)3 = 12/color(blue)3#

Therefore,
#x = 4#

Hope this helps!

#x=4#

We can start by dividing both sides by #3# to get

#x-2=2#

To completely isolate #x#, we can add #2# to both sides to get

#x=4#
