X - y = 1....multiply by -5
5x - 4y = 0
---------------
-5x + 5y = -5 (result of multiplying by -5)
5x - 4y = 0
---------------add
y = -5
x - y = 1
x - (-5) = 1
x + 5 = 1
x = 1 - 5
x = -4
solution is (-4,-5)
Answer:
x=-24 is the correct answer
-4n-8=-12n+8
-4n+12n=8+8
collect the like terms
8n=8+8 then you add 8+8
8n=16 divide both sides by 8
n=2
