Question

2x - 7y = 11; x= -1,0, 1

Answer 1

Fow x=-1

`\begin{gathered} 2x-7y=11 \\ 2(-1)-7y=11 \\ -2-7y=11 \\ -7y=13 \\ y=-(13)/(7) \end{gathered}`

Fow x=0

`\begin{gathered} 2x-7y=11 \\ 2\cdot0-7y=11 \\ -7y=11 \\ y=-(11)/(7) \end{gathered}`

For x=1

`\begin{gathered} 2x-7y=11 \\ 2\cdot1-7y=11 \\ -7y=9 \\ y=-(9)/(7) \end{gathered}`
