Hi there!
To solve this, we need to find the value of one variable and substitute it into the equation to find the other:
6x + y = -7
y = -7 - 6x
5x - 2y = -20
5x - 2(-7 - 6x) = -20
5x + 14 + 12x = -20
17x = -34
x = -2
Now that we know the value of x, we can plug it in again to find the value of y:
x = -2
6x + y = -7
6(-2) + y = -7
-12 + y = -7
y = 5
So, the answer is x = -2 and y = 5.
Hope this helps!
