Find the value of y in the linear equations in two variables 2x-y-5=0 at x=3,7,-1, 0

$\huge \cal \color{red}{\dag{ \underline {\underline{Answer}}}}$

If x = 3, y = 1

If x = 7, y = 9

If x = -1, y = -7

If x = 0, y = -5

$\huge \cal \color{red}{\dag{ \underline {\underline{Steps}}}}$

If x = 3

2 x 3 - y = 5

6 - y = 5

6 - 5 = y

y = 1

If x = 7

2 x 7 - y = 5

14 - 5 = y

y = 9

If x = -1

2 x -1 - y = 5

-2 - y = 5

-2 - 5 = y

y = -7

If x = 0

2 x 0 - y = 5

0 - y = 5

y = -5
