Step 5.3.1.1

Subtract $965$ from both sides of the equation.

$149 y = 816 - 965$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

Step 5.3.1.2

Subtract $965$ from $816$ .

$149 y = - 149$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

$149 y = - 149$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

Step 5.3.2.3.1

Divide $- 149$ by $149$ .

$y = - 1$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

$y = - 1$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

$y = - 1$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

$y = - 1$

$x = \frac{7 y + 103}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

$y = - 1$

Step 6.2.1.1.1

Multiply $7$ by $- 1$ .

$x = \frac{- 7 + 103}{12}$

$y = - 1$

$z = \frac{y}{24} - \frac{47}{24}$

Step 6.2.1.1.2

Add $- 7$ and $103$ .

$x = \frac{96}{12}$

$y = - 1$

$z = \frac{y}{24} - \frac{47}{24}$

$x = \frac{96}{12}$

$z = \frac{y}{24} - \frac{47}{24}$

Step 6.2.1.2

Divide $96$ by $12$ .

$x = 8$

$y = - 1$

$z = \frac{y}{24} - \frac{47}{24}$

$x = 8$

$y = - 1$

$z = \frac{y}{24} - \frac{47}{24}$

$x = 8$

$y = - 1$

$z = \frac{y}{24} - \frac{47}{24}$

Step 6.3

Replace all occurrences of $y$ in $z = \frac{y}{24} - \frac{47}{24}$ with $- 1$ .
