ANSWER

The solution is
(-4,-1)


EXPLANATION

The given equations are:

2x + 5y =  - 13...(1)

and

3x - 4y =  - 8...(2)


We multiply equation 1 by 3 to get,

6x + 15y =  - 39...(3)

We multiply equation 2 also by 2 to get,

6x - 8y =  - 16...(4)

We subtract equation 4 from equation 3 to get,


23y =  - 23
This implies that,

y =  - 1

We put this value of y into any of the equations say equation 2

3x - 4( - 1) =  - 8
Simplify

3x + 4 =  - 8
Group like terms
3x =  - 8 - 4
Simplify,

3x =  - 12

Divide both sides by 3 to get,

x =  - 4


Therefore the solution is
(-4,-1)

The correct answer is option D.
