Answer:
y = 0
Step-by-step explanation:
We assume you want to find y such that ...
Dividing the second equation by 2, we can write an expression for x.
x +2y = -2
x = -2y -2
Substituting this into the first equation gives ...
y = 3(-2y -2) +6
y = -6y -6 +6 . . . eliminate parentheses
7y = 0 . . . . . . . . . add 6y
y = 0 . . . . . . . . . . divide by 7
The value of y in the system of equations is 0.
