Step 1.1

Subtract

3

$3$ from both sides of the equation.

- n = 10 - 3

$- n = 10 - 3$

Step 1.2

Subtract

3

$3$ from

10

$10$ .

- n = 7

$- n = 7$

- n = 7

$- n = 7$

Step 2

Divide each term in

- n = 7

$- n = 7$ by

- 1

$- 1$ and simplify.

Step 2.1

Divide each term in

- n = 7

$- n = 7$ by

- 1

$- 1$ .

\frac{- n}{- 1} = \frac{7}{- 1}

$\frac{- n}{- 1} = \frac{7}{- 1}$

Step 2.2

Simplify the left side.

Step 2.2.1

Dividing two negative values results in a positive value.

\frac{n}{1} = \frac{7}{- 1}

$\frac{n}{1} = \frac{7}{- 1}$

Step 2.2.2

Divide

n

$n$ by

1

$1$ .

n = \frac{7}{- 1}

$n = \frac{7}{- 1}$

n = \frac{7}{- 1}

$n = \frac{7}{- 1}$

Step 2.3

Simplify the right side.

Step 2.3.1

Divide

7

$7$ by

- 1

$- 1$ .

n = - 7

$n = - 7$

n = - 7

$n = - 7$

n = - 7

$n = - 7$
