Question

If x= a , y= b is the solution of the equations x - y = 2 and x+ y = 4 , then the values of a and b are , respectively....

pls show the solution.....​

Answer 1

Answer:

a = 3 , b = 1.

Step-by-step explanation:

Given,

        x = a and y = b, so whatever the values of x and y are the values of a and b respectively.

Here,

⇒ x - y = 2

⇒ x = 2 + y           ...( 1 )

⇒ x + y = 4

⇒ ( 2 + y ) + y = 4

⇒ 2 + y + y = 4

⇒ 2 + 2y = 4

⇒ 2y = 4 - 2

⇒ 2y = 2

⇒ y = 1

Thus,

        x = 2 + y

           = 2 + 1

           = 3

Hence a = 3 and b = 1
