x = 20

Explanation:

Begin by leaving the x term on the left and placing numeric terms on the right.
We can do this by adding 3 to both sides of the equation.

#x/4cancel(-3)color(red)cancel(+3)=2color(red)(+3)#

we now have #x/4=5#

which is the same as #x/4=5/1#

and cross-multiplying gives.

#(1xx x)=(4xx5)rArrx=20#

a quick check shows that #20/4-3=5-3=2#
