Question

-8x + y = -6 =4x – 2y = 12

Answer 1

Let:

`\begin{gathered} -8x+y=-6_{\text{ }}(1) \\ -4x-2y=12_{\text{ }}(2) \end{gathered}`

Using elimination method:

`\begin{gathered} (1)-2(2)\colon \\ -8x-(-8x)+y-(-4y)=-6-24 \\ 5y=-30 \\ y=-(30)/(5) \\ y=-6 \end{gathered}`

Replace the value of y into (1):

`\begin{gathered} -8x-6=-6 \\ -8x=-6+6 \\ -8x=0 \\ x=(0)/(-8) \\ x=0 \end{gathered}`
