You can put this solution on YOUR website!
x-y = -4
3x-6y = -6
...
Multiply the first equation by 3 and subtract the two equations
3(x-y = -4) to get 3x - 3y = -12
subtracting to get
3x - 3x - 3y - -6y = -12 - -6
3y = -6

...
Substitute y into the first equation and solve for x
x - -2 = -4
x + 2 = -4
x = -4 - 2
highlight_green%28x=-6%29
