This is not a calculus question. It is algebra.
There will only be an answer in this case when 5 < x < 3. You can convince yourself of that graphically. You have two Vshaped functions touching the x axis at x = 5 and x = 3. They have mutually parallel sides and they only intersect in one place.
In that region between 5 and +3, the equation becomes
3  2x  2x 5 = 0
4x = 2
Therefore,
x = 1/2
