Question

plz solve this que.....​

Answer 1

Step-by-step explanation:

(2x+7y=3)×3

(3x-5y=2)× 2

and subtract

6x+21y=9

-6x+10y=- 4

y= 5/31

x=87/3

Answer 2

=> 2x + 7y = 3

x = (3 - 7y)/2 ----------(1)

=> 3x - 5y = 2 ------------(2)

Putting (1) in (2)

3 (3-7y)/2 - 5y = 2

(9 - 21y)/2 - 5y = 2

9 - 21y - 10y = 4

9 - 31 y = 4

5 = 31y

y = 5/31

x = 87/3
