Answer:
No solutions
Step-by-step explanation:
If we try to solve this system for y at x = 1, we get an impossible situation:
[tex]y=-7(1)+8=-7+8=1\\y=-7(1)-8=-7-8=-15\\1=-15[/tex]
Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.
