2x-3y=7
5x+y=9​

Answer 1

2x-3y=7 ......(1)

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

Multiplying equation (2) by 3,

15x+3y=27 ........(3)

Adding equation (1) and (3),

15x+3y=27

2x-3y=7 we get,

17x =34

x = 34/17

x =2

put x=2 in equation (2),

5x+y=9

5×2+y=9

10+y=9

y=9-10

y=-1

x=2, y=-1 is the solution for the given equation…
