$v = \frac{x - y}{z}$

Step 1

Rewrite the equation as $\frac{x - y}{z} = v$ .

$\frac{x - y}{z} = v$

Step 2

Multiply both sides by $z$ .

$\frac{x - y}{z} z = v z$

Step 4.2.2.1

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{v z}{- 1} + \frac{- x}{- 1}$

Step 4.2.2.2

Divide $y$ by $1$ .

$y = \frac{v z}{- 1} + \frac{- x}{- 1}$

Step 4.2.3.1.1

Move the negative one from the denominator of $\frac{v z}{- 1}$ .

$y = - 1 \cdot (v z) + \frac{- x}{- 1}$

Step 4.2.3.1.2

Rewrite $- 1 \cdot (v z)$ as $- (v z)$ .

$y = - (v z) + \frac{- x}{- 1}$

Step 4.2.3.1.3

Dividing two negative values results in a positive value.

$y = - v z + \frac{x}{1}$

Step 4.2.3.1.4

Divide $x$ by $1$ .

$y = - v z + x$
