$z = 3$

$y = - \frac{8}{5} + \frac{11 z}{5}$

$x = - 1$

$z = 3$

$y = - \frac{8}{5} + \frac{11 z}{5}$

Replace all occurrences of $z$ in $y = - \frac{8}{5} + \frac{11 z}{5}$ with $3$ .

$y = - \frac{8}{5} + \frac{11 (3)}{5}$

$x = - 1$

$z = 3$

Simplify the right side.

Simplify $- \frac{8}{5} + \frac{11 (3)}{5}$ .

Combine the numerators over the common denominator.

$y = \frac{- 8 + 11 (3)}{5}$

$x = - 1$

$z = 3$

Simplify the expression.

Multiply $11$ by $3$ .

$y = \frac{- 8 + 33}{5}$

$x = - 1$

$z = 3$

Add $- 8$ and $33$ .

$y = \frac{25}{5}$

$x = - 1$

$z = 3$

Divide $25$ by $5$ .

$y = 5$

$x = - 1$

$z = 3$

$y = 5$

$x = - 1$

$z = 3$

$y = 5$

$x = - 1$

$z = 3$

$y = 5$

$x = - 1$

$z = 3$

$y = 5$

$x = - 1$

$z = 3$

Step 7

The solution to the system is the complete set of ordered pairs that are valid solutions.

$(- 1, 5, 3)$

Step 8

The result can be shown in multiple forms.

Point Form:

$(- 1, 5, 3)$

Equation Form:

$x = - 1, y = 5, z = 3$

Solve by Substitution x-y+3z=3 , 2x+y-z=0 , 2x+3y-5z=-2
