Answer:
Step-by-step explanation:
-x + 2y = 8
-2x + y = -5
2x - 4y = -16
-3y = -21
y = 7
-x + 14 = 8
-x = -6
x = 6
(6,7)
25 and 4
10 and 10
100 and 1
20 and 5
the answer would be -6=-6
I think so. Just check your work backwards. Plug in x for 5 and see if you come to an answer that you know is 100% correct.
Hope that helps!
