Answer 1

Answer:

solve the following pairs of linear equation by elimination

method x+3y=4,2x+5y=9

Sorry, it's too hard

Answer 2

Answer:

x + 3y = 4 ........( 1 )

2x + 5 y = 9 ......( 2 )

let, multiplying Eq. 1 by 5 and Eq. 2 by 3

hence, 5x + 15 y = 20........(3)

6x + 15 y = 27 .........(4)

subtracting , eq. (3) from Eq. (4)

: 6x + 15 y = 27

- 5x - 15 y = -20

x = 7

hence, y = -1

follow me friend , I gave you the details answer.
