Answer 2

Step-by-step explanation:

Answer By Elimination Method Is...

3x + 4y = 7

2x + 5y = 14

(I)...

first We Create All Pair Same.

3x + 4y×5 = 7×5

2x + 5y×4 = 14×4

(ii).... (Solving)

3x + 20y = 35

2x + 20y = 56

(iii)..... By Eliminating Trick (+ - )

-x = -21

x = 21 Is Correct Answer..
