Question

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

Answer 1

Fow x=-1

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

Fow x=0

$\begin{gathered} 2x-7y=11 \\ 2\cdot0-7y=11 \\ -7y=11 \\ y=-\frac{11}{7} \end{gathered}$

For x=1

$\begin{gathered} 2x-7y=11 \\ 2\cdot1-7y=11 \\ -7y=9 \\ y=-\frac{9}{7} \end{gathered}$
