2x+3y=-6 ----->eq.1

-2x-5y=14

2x+5y= -14 ----->eq.2

Now,

2x+3y=-6

2x+5y=-14

--------------

-2y=8

y=8/-2

y= -4

Replacing in eq.

2x+3y=-6

2x+3(-4)=-6

2x-12=-6

2x=6

x=3

Now,.

Replacing x & y value in any eq.

2(3)+3(-4)=-6

6+(-12)=-6

-6=-6

Answer 2

Answer:

2x+3y=-6 ----->eq.1

-2x-5y=14

2x+5y= -14 ----->eq.2

Now,

2x+3y=-6

2x+5y=-14

--------------

-2y=8

y=8/-2

y= -4

Replacing in eq.

2x+3y=-6

2x+3(-4)=-6

2x-12=-6

2x=6

x=3

Now,.

Replacing x & y value in any eq.

2(3)+3(-4)=-6
