Here is the problem: 4x + 4y = 4
-3x + 5y = -51
I have tried multiplying, and substitution and I can't figure out how to get the correct answers.
Here is what I have done so far:
3(4x + 4y=4) 12x + 12y = 12
4(3x - 5y = 51) 12x - 20y = 204
-8y = 216
y = 27
I know that that's not right, but I don't know what I did wrong!
