Solve for x x=2y-4 7x+5y=-66

$x = 2 y - 4$ $7 x + 5 y = - 66$

The simplified system is the arbitrary solution of the original system of equations.

$y = \frac{x}{2} + 2$

$y = - \frac{66}{5} - \frac{7 x}{5}$

Simplify the right side.

Reorder $- \frac{66}{5}$ and $- \frac{7 x}{5}$ .

$y = - \frac{7 x}{5} - \frac{66}{5}$

$y = \frac{x}{2} + 2$

$y = - \frac{7 x}{5} - \frac{66}{5}$

$y = \frac{x}{2} + 2$
