What is the value of the y variable in the solution to the following system of equations?

3x − 6y = 3

7x − 5y = −11

−2
−3
x can be any number as there are infinitely many solutions to the system.
There is no x value as there is no solution to the system

3x − 6y = 3          multiply by 7
7x − 5y = −11        mutiply by 3
new equations.
21x-42y=21
21x-15y=-33
21+42y=15y-33
7+14y=5y-11
14y-5y=-7-11
9y=-18
y=-2
