#x=12#

Explanation:

Because the denominators need to be the same number, so you multiply #x/2# by #3/3# and so it will equal

#(3x)/6-x/6=4#

Then, you subtract and it will equal

#(2x)/6=4#

Then, you follow PEMDAS and multiply #6# on both sides to eliminate the divide by 6, so it would equal

#2x=24#

You divide by #2# on both sides and #x# will equal #12#.
