Ответ:
x=4, y=1
Step-by-step explanation:
Because y=y, you can make an equation that is -x+5=2x-7. Then add the x to the right side, so it would be 5=3x-7. Then add the 7 to the left side to get all of the numbers in one place. So it would be 12=3x. Divide by 3 on both sides and you get x=4. Then plug x into either one of the original equations. Both equations should get you the same answer for y. Y=-4+5. Y=1. And the other equation. Y=2x-7, y=8-7. Y=1
