Answer 2

Step-by-step explanation:

2x+ 3y = 12 ---------- (1)

3x + 2y = 13 ----------(2)

In equation 1 multiply by 3.& in equation 2 multiply by 2 .

6x + 9y = 36

6x + 4y = 26

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

5y = 10

y = 10/5 =2

In equation 1 put the value of y.

2x + 3×2 = 12

2× = 12 - 6

2× = 6

× = 6/2 = 3

so ,

x= 3 , y = 2 Ans .
