Answer 1

Given Equations :

✿  10x - 7y = -1 --------------- [1]

✿  2x + 7y = 25 -------------- [2]

Adding Equations [1] and [2], We get :

⇒ (10x - 7y) + (2x + 7y) = -1 + 25

⇒ 12x = 24

⇒ x = 2

Substituting x = 2 in Equation [1], We get :

⇒ 10(2) - 7y = -1

⇒ 7y = 20 + 1

⇒ 7y = 21

⇒ y = 3

The Solution of the Given System of Equations is : (x , y) = (2 , 3)
