Basic Math Examples

- 12 = - 8 z + 12

$- 12 = - 8 z + 12$

Step 1

Rewrite the equation as

- 8 z + 12 = - 12

$- 8 z + 12 = - 12$ .

- 8 z + 12 = - 12

$- 8 z + 12 = - 12$

Step 2

Move all terms not containing

z

$z$ to the right side of the equation.

Step 2.1

Subtract

12

$12$ from both sides of the equation.

- 8 z = - 12 - 12

$- 8 z = - 12 - 12$

Step 2.2

Subtract

12

$12$ from

- 12

$- 12$ .

- 8 z = - 24

$- 8 z = - 24$

- 8 z = - 24

$- 8 z = - 24$

Step 3

Divide each term in

- 8 z = - 24

$- 8 z = - 24$ by

- 8

$- 8$ and simplify.

Step 3.1

Divide each term in

- 8 z = - 24

$- 8 z = - 24$ by

- 8

$- 8$ .

\frac{- 8 z}{- 8} = \frac{- 24}{- 8}

$\frac{- 8 z}{- 8} = \frac{- 24}{- 8}$

Step 3.2

Simplify the left side.

Step 3.2.1

Cancel the common factor of

- 8

$- 8$ .

Step 3.2.1.1

Cancel the common factor.

$\frac{- 8 z}{- 8} = \frac{- 24}{- 8}$

Step 3.2.1.2

Divide

$z$ by

$1$ .

$z = \frac{- 24}{- 8}$

$z = \frac{- 24}{- 8}$

$z = \frac{- 24}{- 8}$

Step 3.3

Simplify the right side.

Step 3.3.1

Divide

$- 24$ by

$- 8$ .

$z = 3$

$z = 3$

$z = 3$
