Answer 1

Answer:

how it helps you (⌒_⌒;)✌✌

Step-by-step explanation:

Given pair of linear equations is x1 − y1 =1..(i)

x1+ y1 =7...(ii)

Adding Eq.(i) and Eq.(ii), we get

x1 − y1 + x1 + y1 =1+7

⇒ x1 + x1 =8

⇒ 8^2 =x

⇒x= 4^1

On putting x= 4^1

in Eq. (ii) we get

x1 + y1 =

⇒ 4^1^1 + y1 =7

4+ y1 =7

⇒ y1 =7−4=3

y= 3^1

Hence, x= ^41 and 3^1

, which is required solutions
