Question

Solve the system by substitution.

Answer 1

first equation can be rewritten as \(y=-2x-11\) substitute in to second equation get
\[3x-4(-2x-11)=11\]
\[3x+8x+44=11\]
\[11x=-33\]
\[x=-3\] and again you only have one choice so you do not need to find \(y\)

Answer 2

so is it (-5,-3) or (-3,-5)

Answer 3

we found \(x\) so it is \((-3,-5)\)
