Question

write two solution of equation 2x-y=7​

Answer 1

2x-y=7

y=2x-7

two solutions can be

y=1,3

x=4,5

Answer 2

Answer:

y=-5 , x=5

Step-by-step explanation:

Firstly, let x=1,then

2x-y=7

2(1)-y=7

2-y=7

-y=7-2

-y=5

y=-5.

and now, let y=3

2x-y=7

2x-3=7

2x=7+3

2x=10

x=10/2

x=5

hope this will help you!
