Answer:B
Step-by-step explanation:
Just did it on math nation
-2x + 6y = 6
6y - 6 = 2x
6(y-1) = 2x
(1/2) * 6(y-1) = 2x * (1/2)
x = 3(y-1)
------------
If, x = 3(y-1),
-7 * 3(y-1) + 8y = -5
-21 * (y-1) + 8y = -5
-21y + 21 + 8y = -5
21 + 5 = 21y - 8y
26 = 13y
y = 26/13
Therefore: y=2.
----------
If y=2,
x = 3(2-1) = 3
-----------
Answers:
x=3 and y=2.
It’s the last one. Six.
