Answer 2

The four solution is $(1,\frac{9}{7}),(2, \frac{6}{7}),(-1,\frac{15}{7})\ and\ (-2,\frac{18}{7})$

Step-by-step explanation:

Write Four solution for $3x+7y=12$

∴ $3x+7y=12$

⇒$7y=12-3x$

⇒$y=\frac{12-3x}{7}$

For $x=1$,

⇒$y=\frac{12-3\times 1}{7}$

⇒$y=\frac{12-3}{7}$

⇒$y=\frac{9}{7}$

For $x=2$,

⇒$y=\frac{12-3\times 2}{7}$

⇒$y=\frac{12-6}{7}$

⇒$y=\frac{6}{7}$

For $x=-1$,

⇒$y=\frac{12-3\times -1}{7}$

⇒$y=\frac{15}{7}$

For $x=-2$,

⇒$y=\frac{12-(3\times -2)}{7}$

⇒$y=\frac{18}{7}$

So, The four solution is $(1,\frac{9}{7}),(2, \frac{6}{7}),(-1,\frac{15}{7})\ and\ (-2,\frac{18}{7})$
