Plz refer to the attachments for detailed answer..

Answer 2

Answer:

By elimination method

equation (1) | equation (2)

3x-5y-4=0. | 9x=2y+7

3x-5y=4. | 9x-2y=7

Multiply equation (1) by 3

9x-15y=12

Equating both equation

9x-15y=12

9x-2y=7

- + -

______________

-13y=5

y=-5/13

put value of y in equation (1)

9x=2y+7

9x=2 (-5/13)+7

9x=-10/13+7

9x=(-10+91)/13

9x=81/13

x=81/13*1/9

x=9/13.

Hope it will help you.
