Question

Question is in the picture. No need for explanation. Just the answer is needed.

Answer 1

your answer is
x=-3 or y=-11

Answer 2

We have

`\begin{gathered} y=7x+10 \\ y=-4x-23 \end{gathered}`

we make the next equality

`7x+10=-4x-23`

then we sum like terms

`7x+4x=-23-10`
`\begin{gathered} 11x=-33 \\ x=(-33)/(11)=-3 \end{gathered}`

Then we substitute the value of x in the first equation

`\begin{gathered} y=7(-3)+10 \\ y=-21+10 \\ y=-11 \end{gathered}`

ANSWER

x=-3

y=-11
