2y + 6

Answer 1

helpp!! plzz!!

Answer 2

ok google is open 24/7 !!

Answer 3

we have first equation as
\[-x+2y=-6\]
Let's find x from this , which we'll substitute in 2nd to find y
subtract both sides by 2y, we get
\[-x=-6-2y\]
multiply both sides by -1, we get
\[x=6+2y \]or \[x= 2y+6\]
this we have to substitute in 2nd to find y. This is your answer
