Question

refer to the attachment ⬆️

Solution ⬇️

➡️2x-y=7

✳️x=0.. given

✍️2(0)-y=7

✍️0-y=7

✍️-y=7-0

✍️y=-7

✳️(x=0,y=-7)

➡️2x-y=7

✳️y=-3.. given

✍️2x-(-3)=7

✍️2x+3=7

✍️2x=7-3

✍️2x=4

$= = > x = \frac{4}{2} = \frac{2}{1} = 2$

✳️(x=2,y=-3)

➡️2x-y=7

✳️x=3.. given

✍️2(3)-y=7

✍️6-y=7

✍️-y=7-6

✍️-y=1

✍️y=-1

✳️(x=3,y=-1)

➡️2x-y=7

✳️y=-5

✍️2x-(-5)=7

✍️2x+5=7

✍️2x=7-5

✍️2x=2

$= = > x = \frac{2}{2} = 1$

✳️(x=1,y=-5)
