add the two equations
11y=55
y=5
now sub 5 in for y
x+15=23
x=8

Add the two equations, thereby "eliminating" x:
11y = 55
y = 5

Then, replace y = 5 into either equation to obtain x = 8.

Hi

 x + 3y = 23

-x + 8y = 32     |'Adding the two EQs' to eliminate x

     11y = 55

       y = 5  and x = 8   (23-3*5)
