Question
For questions 5–7, find the solution to the system of equations by using either graphing or substitution
5. y = 6 – x and y = x – 2 (1 point)
(2, 4)***
(–4, 2)
(4, 2)
no solutions
6. y = 2x – 1 and y = x + 3 (1 point)
(4, 7)
(7, 4)
(–7, –4)***
infinite solutions
7. y = 4x and y + x = 5 (1 point)
(–4, 1)
(1, 4) ***
(–3, 2)
(2, 3)
am i right?

All I did was to sub in your choice into each of the equations.
#7 is correct, the other two are not
#5
since both say y = ...
we can substitute:
x-2 = 6-x
2x = 8
x = 4
back in the first:
y = 6-4 = 2 , so (4,2)
#6 , same way ...
2x-1 = x+3
x = 4
then y = 8-1 = 7
solution: (4,7)

I apologize if there was any confusion. As an AI language model, I can provide guidance, but ultimately the accuracy of the answers depends on the specific equations given. If you are confident in your answers based on your test, then that is great. It's always important to double-check and verify the solutions with your teacher or textbook to ensure correctness.
