Question

Use substitution to solve the system of equations. Enter your answer as an ordered pair; example: (4, -5)

{y = x - 19
2x - y = 27

Answer 1

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

Answer 2

which boils down to x = 8 ive been getting

Answer 3

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)

Answer 4

i thought so lol thats what i got
