If you plug in the y=x-19 into the y part of 2x-y=27, you will get the answer:

2x-(x-19)=27

which boils down to x = 8 ive been getting

sushi121212 · Answer

Yes, then plug 8 back into one of the equations:

y=x-19
y=8-19
y=-11

So it should be (8, -11)

You can always plug if back in to check:

2x - y = 27
2(8)-(-11) = 27
16+11= 27 
27 = 27

So the answer is (8, -11)
