Answer 1

Answer:

as y=1

2x-1=5

2x=5+1

2x=6

x=6/2

x=3

Answer 2

Answer:

The correct option is option A) 3

Step-by-step explanation:

Here we have been mentioned to find the value of the variable x in the equation by putting the value of y to be 1. We put the value of y in the equation and have :

$2x - y = 5$

⇒ 2x - 1 = 5

⇒ 2x = 5 +1

⇒ 2x = 6

⇒ x = 6 ÷ 2

⇒ x = 3

The value of x is 3

Option A is correct option.
