3. uzumakhi Group Title

in second equation take y to right side then multiple second equation with 2

4. ihavemathquestions Group Title

I think the answer is either (-1, 3) or (3, -1) or (-3, -1) or (-1, - 3)

5. Compassionate Group Title

Put each equation in Y intercept form. Plug in a few numbers and graph.

6. uzumakhi Group Title

@Compassionate it can be done simply by eliminating Y

7. Compassionate Group Title

y = x + 2 y = 2x + 5 Plug in valies 1-2 for x.

$-2x=2y-4\quad \implies\quad -2x+4=2y\quad\implies\quad y=-x+4$ $2x-y=-5\quad\implies\quad2x+5=y\quad\implies\quad y=2x+5$
