Step 1.1

Subtract

4

$4$ from both sides of the equation.

- n = 12 - 4

$- n = 12 - 4$

Step 1.2

Subtract

4

$4$ from

12

$12$ .

- n = 8

$- n = 8$

- n = 8

$- n = 8$

Step 2

Divide each term in

- n = 8

$- n = 8$ by

- 1

$- 1$ and simplify.

Step 2.1

Divide each term in

- n = 8

$- n = 8$ by

- 1

$- 1$ .

\frac{- n}{- 1} = \frac{8}{- 1}

$\frac{- n}{- 1} = \frac{8}{- 1}$

Step 2.2

Simplify the left side.

Step 2.2.1

Dividing two negative values results in a positive value.

\frac{n}{1} = \frac{8}{- 1}

$\frac{n}{1} = \frac{8}{- 1}$

Step 2.2.2

Divide

n

$n$ by

1

$1$ .

n = \frac{8}{- 1}

$n = \frac{8}{- 1}$

n = \frac{8}{- 1}

$n = \frac{8}{- 1}$

Step 2.3

Simplify the right side.

Step 2.3.1

Divide

8

$8$ by

- 1

$- 1$ .

n = - 8

$n = - 8$

n = - 8

$n = - 8$

n = - 8

$n = - 8$
