We will solve this one using elimination so we can find what one variable =;
We begin by adding the two equations toogether;
5x+5y=40
-5x+4y=-4
----------
9y=36
Divide both sides by 9

y=4
Now we have what y=, so now we can solve for x;
5x+5(4)=40
5x+20=40
5x=40-20
5x=20
x=4
So now we have;
x=4
y=4
Hope you understand
=)
