Question

Which equation could be the other equation in this system ?

Answer 1

Given:

`8x-5y=-2`

To find the equation that could be the other equation in this system:

Multiplying -2 on both sides, we get

`\begin{gathered} -2(8x-5y)=-2(-2) \\ -16x+10y=4 \end{gathered}`

So, the equation that could be the other equation in this system is,

`-16x+10y=4`
