Solve each system to find the answer

Given:

The system of equations is

To find:

The solution of given system of equations.

Solution:

We have,

       ...(i)

        ..(ii)

Multiply (i) by 5 and (ii) by 4.

       ...(iii)

        ..(iv)

Adding (iii) and (iv), we get

Divide both sides by 13.

Put g=6 in (i).

Divide both sides by 4.

So, the solution of the system of equation is (6,-5).

Therefore, the correct option is A.
