Cancel the common factor.

$\frac{3 y}{3} = \frac{7}{3}$

Step 1.2.1.2

Divide $y$ by $1$ .

$y = \frac{7}{3}$

Step 2

Since $y = \frac{7}{3}$ is a horizontal line, the y-values are $\frac{7}{3}$ for any value of x. Choose any three x-values to obtain three solutions.

$(0, \frac{7}{3}), (1, \frac{7}{3}), (2, \frac{7}{3})$
