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+64y=5
=>6y=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
