$x (n) = 3 n - 4$

Step 1

Divide each term in $x n = 3 n - 4$ by $n$ .

$\frac{x n}{n} = \frac{3 n}{n} + \frac{- 4}{n}$

Step 2

Step 2.1.1

Cancel the common factor.

$\frac{x n}{n} = \frac{3 n}{n} + \frac{- 4}{n}$

Step 2.1.2

Divide $x$ by $1$ .

$x = \frac{3 n}{n} + \frac{- 4}{n}$

$x = \frac{3 n}{n} + \frac{- 4}{n}$

$x = \frac{3 n}{n} + \frac{- 4}{n}$

Step 3.1.1.1

Cancel the common factor.

$x = \frac{3 n}{n} + \frac{- 4}{n}$

Step 3.1.1.2

Divide $3$ by $1$ .

$x = 3 + \frac{- 4}{n}$

$x = 3 + \frac{- 4}{n}$

Step 3.1.2

Move the negative in front of the fraction.

$x = 3 - \frac{4}{n}$

$x = 3 - \frac{4}{n}$

$x = 3 - \frac{4}{n}$
