Answer 2

↪ Equation :
x-y = 5 ------(1)

3x + 2y = 25 -----(2)


▶Method of Solution ▶

Solving By Elimination Method ↙

x-y = 5

3x + 2y = 25

Step : Multiply Equation (1) by 3

↪ Multiply Equation (2) by 1

↪x-y = 5 × (3)

3x + 2y = 25 × (1)
--------------------------

▶ 3x-3y = 15

▶ 3x+2y = 25

----------------------

-5y = - 10

•°• y = 2

↪Substitute the Value of Y in the Equation (1)

↪ x - y = 5

↪ x -2 = 5

↪ x = 5+2

↪ x = 7


Hence, Value of x and y are 7 and 2 Respectively!
