Answer 1

Answer 2

you want to solve it, or check the solutions?

Answer 3

we can rewrite the second equation
\[-4x-4y=28\] by dividing by \(-4\) and get
\[x+y=-7\] or \(y=-x-7\)
then use that to solve in the first equation

Answer 4

\[3y=4x+7\]
\[3(-x-7)=4x+7\]
\[-3x-21=4x+7\]
\[-28=7x\]
\[x=-4\] so now we have \(x=-4\) i guess we are done since you only have one option

Answer 5

must be \((-4,-3)\)
