Basic Math Examples

17 = 9 - a

$17 = 9 - a$

Step 1

Rewrite the equation as

9 - a = 17

$9 - a = 17$ .

9 - a = 17

$9 - a = 17$

Step 2

Move all terms not containing

a

$a$ to the right side of the equation.

Step 2.1

Subtract

9

$9$ from both sides of the equation.

- a = 17 - 9

$- a = 17 - 9$

Step 2.2

Subtract

9

$9$ from

17

$17$ .

- a = 8

$- a = 8$

- a = 8

$- a = 8$

Step 3

Divide each term in

- a = 8

$- a = 8$ by

- 1

$- 1$ and simplify.

Step 3.1

Divide each term in

- a = 8

$- a = 8$ by

- 1

$- 1$ .

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

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

Step 3.2

Simplify the left side.

Step 3.2.1

Dividing two negative values results in a positive value.

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

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

Step 3.2.2

Divide

a

$a$ by

1

$1$ .

a = \frac{8}{- 1}

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

a = \frac{8}{- 1}

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

Step 3.3

Simplify the right side.

Step 3.3.1

Divide

8

$8$ by

- 1

$- 1$ .

a = - 8

$a = - 8$

a = - 8

$a = - 8$

a = - 8

$a = - 8$

17 = 9 - a

$17 = 9 - a$
