Question

Can someone please explain how to solve this step by step so I could learn how to do this, if I don’t figure this out I’m literally gonna shoot myself

Answer 1

`2x+2y=-8 \implies x+y=-4 \implies y=-4-x`

We can substitufe this result into the second equation.

`-10x-5(-4-x)=-5 \\ \\ -10x+20+5x=5 \\ \\ -5x+20=5 \\ \\ -5x=-15 \\ \\ x=3 \implies y=-4-3=-7`

`\therefore` The solution is
`(3,-7)`.
