Question

I’m really confused on this problem. I nee

Answer 1

$2x + ( - 2x - 6) = 5 \\ - 6 = 5$
No solution

Answer 2

Y= -2x-6
2x+y=5 so then y= -2x+5

If you look at those two equations and ask yourself when is
y = a number-6 and in the same time
y = same number +5
The answer is never, so the system of equations has no solutions
