Question

Find the value of x in the equation 2x - y = 7 if y=-3 ​

Answer 1

Answer:

2x-y=7

=>2x-3=7

=>2x=7-3

=>2x=4

=>x=4/2

=>x=2

Answer 2

Answer:

=> The value of x is 2

Step-by-step explanation:

Given that:-

$2x-y=7$

If y = -3

To find - The value of x,

For solving we have to put the value of y in the given expression,

So, we will get

$=> 2x-y=7$

$=> 2x-(-3)=7$

$=> 2x+3=7$

$=> 2x=7-3$

$=>2x=4$

Divide both sides by $2$ we get

=> x = 2

Hence, the value of x is 2.
