Easier to arrange into both the same form.

3y=x+5
3y+(-x)=x+5+(-x)
-x+3y=x+(-x)+5
-x+3y=0+5
-x+3y=5.

The other equation is already in the same (standard) form. Easiest choice of factor to use for the transformed first equation is NEGATIVE 3. You would then add the two equations. This will eliminate x terms.
