<pre>
{{{graph( 330, 330, -10.5, 10.5, -10.5, 10.5,
          sqrt(3x-5), sqrt(4-7x)
)}}}


Plot y1 = {{{sqrt(3x-5)}}} (red) and y2 = {{{sqrt(4-7x)}}} (green)

This equation HAS NO solution in real domain.


In real domain the domains of the left side and the right side are disjoint sets of real numbers, so the common solution is IMPOSSIBLE.


The solutions found by other tutors are valid in complex domain only (when you allow to square roots to be complex numbers).
