Question

determine the solution to the system. Explain which method you used to determine your solution. 2x+y=-15y-6x=7

Answer 1

`\begin{gathered} 2x+y=-1 \\ 5y-6x=7 \end{gathered}`

This is the system.

We will use the method of elimination to solve it.

So we will multiply the first equation by 3 and add it to the second one, this will gives us.

`8y=4\rightarrow y=(1)/(2)`
`2x+(1)/(2)=-1\rightarrow2x=-(3)/(2)\rightarrow x=-(3)/(4)`
