Answer 2

Solution

Given =》

▪︎ 3x-5y-4=0

▪︎ 9x=2y+7

Explanation =》

3x-5y=4................(1)

9x-2y=7................(2)

Multiply eq. 1 by 3

3( 3x-5y=4)

= 9x-15y= 12................(3)

On subtracting eq 2 from 3

9x -15y = 12

9x - 2y = 7

- + -

————————

13y = 5

y= 5/13

putting y = 5/13 in eq 3

9x-15×5/13 =12

9x - 75/13=12

9x= 231/13

x= 231/117

hope IT HELPs!!
