Question

Answer 1

Pic have the sol. Hope it will help . Read carefully.

Answer 2

8x+5y=9 (multiplying both sides by 2)

16x+10y=18.............(1)

3x+2y=4(multiplying both sides by 5)

15x+10y=20.............(2)

subtracting (ii) from(i)

x=-2

putting value of x in 3x+2y=4

3×-2+2y=4

-6+2y=4

2y=10

y=5
