$3 x - 7 y = 4$ $x + 7 y = 16$

Step 1

Reduce the system.

$y = - \frac{4}{7} + \frac{3 x}{7}, y = \frac{16}{7} - \frac{x}{7}$

Step 2

Simplify the right side.

Step 2.1

Reorder $- \frac{4}{7}$ and $\frac{3 x}{7}$ .

$y = \frac{3 x}{7} - \frac{4}{7}$

$y = \frac{16}{7} - \frac{x}{7}$

$y = \frac{3 x}{7} - \frac{4}{7}$

$y = \frac{16}{7} - \frac{x}{7}$

Step 3

Simplify the right side.

Step 3.1

Reorder $\frac{16}{7}$ and $- \frac{x}{7}$ .

$y = - \frac{x}{7} + \frac{16}{7}$

$y = \frac{3 x}{7} - \frac{4}{7}$

$y = - \frac{x}{7} + \frac{16}{7}$

$y = \frac{3 x}{7} - \frac{4}{7}$
