Question

@Destinymasha @girlover @sammixboo
Please help me with these two problems

Answer 1

So lets start off with the first equation:
\[x - y = -11 \]add y to both sides:
\[x = -11 + y \]Now that we have x, we plug that into the other equation:
\[y + 7 = -2(-11 + y) \]And you solve that for y

Same for the second one:
\[x - y = - 9 \]Add y to both sides:
\[x = -9 + y \]Now plug into first equation:
\[y = 3(-9+y)-1\]And solve for y

Answer 2

All you have to do is solve both equations for y, and you have the answers.
I have to go now, I hope you understand! c:
