Finite Math Examples

- 5 x \cdot 1 + 2 x \cdot 2 = 9

$- 5 x \cdot 1 + 2 x \cdot 2 = 9$ ,

- 2 x \cdot 1 + x \cdot 2 = - 5

$- 2 x \cdot 1 + x \cdot 2 = - 5$

Step 1

Divide each term in

- x = 9

$- x = 9$ by

- 1

$- 1$ .

\frac{- x}{- 1} = \frac{9}{- 1}

$\frac{- x}{- 1} = \frac{9}{- 1}$

Step 2

Step 2.1

Dividing two negative values results in a positive value.

\frac{x}{1} = \frac{9}{- 1}

$\frac{x}{1} = \frac{9}{- 1}$

Step 2.2

Divide

x

$x$ by

1

$1$ .

x = \frac{9}{- 1}

$x = \frac{9}{- 1}$

x = \frac{9}{- 1}

$x = \frac{9}{- 1}$

Step 3

Simplify the right side.

Step 3.1

Divide

9

$9$ by

- 1

$- 1$ .

x = - 9

$x = - 9$

x = - 9

$x = - 9$
