Given:

The system of equations is:


-4g-15h=-17


-g+5h=13

To find:

The correct statement that explains the solution process.

Solution:

We have,


-4g-15h=-17


-g+5h=13

To eliminate the variable g, we need same coefficients of g having opposite signs.

The coefficient of g in first equation is -4 and the coefficient of g in bottom equation is -1. If we multiply the bottom equation by -4, then we get 4 as a coefficient of g.


4g-20h=-52 [(i)×(-4)]

After that we can add both equation to eliminate the variable g and then we can solve to h.

She can multiply the bottom equation by -4 and then add the equations to solve for h.

Therefore, the correct option is A.
