Answer:

Given the system of equations


\begin{gathered} 6x-7y=28 \\ 2x+4y=-16 \end{gathered}

We intend to use the elimination method to solve it.

• Multiply the first equation by 2

,

• Multiply the second equation by 6

This gives us:


\begin{gathered} 12x-14y=56 \\ 12x+24y=-96 \end{gathered}

We eliminate x by subtracting.
