You asked 'how' to solve. So I have taken it to a point where you can take over, The layout given is an example of good mathematics.

Explanation:

Given:
5x+3y=2........................................(1)
-x+5y=4.......................................(2)

Rewrite 1 and 2 as:

y= -5/3x+2/3................................(1_a)
y=1/5x+4/5......................................(2_a)

But (1_a) = y = (2_a)

So

-5/3x+2/3 = 1/5x+4/5

This can now be solved by collecting like terms and isolating x.
