Basic Math Examples

7 = 40 - a

$7 = 40 - a$

Step 1

Rewrite the equation as

40 - a = 7

$40 - a = 7$ .

40 - a = 7

$40 - a = 7$

Step 2

Move all terms not containing

a

$a$ to the right side of the equation.

Step 2.1

Subtract

40

$40$ from both sides of the equation.

- a = 7 - 40

$- a = 7 - 40$

Step 2.2

Subtract

40

$40$ from

7

$7$ .

- a = - 33

$- a = - 33$

- a = - 33

$- a = - 33$

Step 3

Divide each term in

- a = - 33

$- a = - 33$ by

- 1

$- 1$ and simplify.

Step 3.1

Divide each term in

- a = - 33

$- a = - 33$ by

- 1

$- 1$ .

\frac{- a}{- 1} = \frac{- 33}{- 1}

$\frac{- a}{- 1} = \frac{- 33}{- 1}$

Step 3.2

Simplify the left side.

Step 3.2.1

Dividing two negative values results in a positive value.

\frac{a}{1} = \frac{- 33}{- 1}

$\frac{a}{1} = \frac{- 33}{- 1}$

Step 3.2.2

Divide

a

$a$ by

1

$1$ .

a = \frac{- 33}{- 1}

$a = \frac{- 33}{- 1}$

a = \frac{- 33}{- 1}

$a = \frac{- 33}{- 1}$

Step 3.3

Simplify the right side.

Step 3.3.1

Divide

- 33

$- 33$ by

- 1

$- 1$ .

a = 33

$a = 33$

a = 33

$a = 33$

a = 33

$a = 33$
