This one is easy. x is already expressed in terms of y in the second equation. You only have to replace the x in the forst equation with the expression from the second equation. You get that:
3*(y+2)-4y=-5
=>3y+6-4y=-5
=>6-y=-5
=>y=11
When we place this value for y in the second equation, we find that
x=11+2=13
So, y=11 and x=13
solve using substitution
3x-4y=-5
x=y+2
