Question

In the linear equation 2x - y = 7, if x = 2, then
what is the value of y?​

Answer 1

Answer:

-3

Step-by-step explanation:

2x-y=7

putting the value of x

x=2

4-y=7

-y=7-4

y=-3

Answer 2

Answer:

=> The value of y is -3.

Step-by-step explanation:

Given that:-

$2x - y = 7$      $...(i)$

If, x = 2

To find - The value of y,

For, solving we need to put the given value of x in the equation for determining the value of y,

Now, plug the value of x as 2 in the equation ( i ), we get

As we have,

$=> 2x - y = 7\\=> 2 (2) - y = 7\\=> 4-y=7\\=> -y = 7-4\\=> -y = 3\\=> y = -3$

Hence, the value of y is -3.
