Basic Math Examples

$y = 19 - q$

Step 1

Rewrite the equation as $19 - q = y$ .

$19 - q = y$

Step 2

Subtract $19$ from both sides of the equation.

$- q = y - 19$

Step 3

Divide each term in $- q = y - 19$ by $- 1$ and simplify.

Step 3.1

Divide each term in $- q = y - 19$ by $- 1$ .

$\frac{- q}{- 1} = \frac{y}{- 1} + \frac{- 19}{- 1}$

Step 3.2

Simplify the left side.

Step 3.2.1

Dividing two negative values results in a positive value.

$\frac{q}{1} = \frac{y}{- 1} + \frac{- 19}{- 1}$

Step 3.2.2

Divide $q$ by $1$ .

$q = \frac{y}{- 1} + \frac{- 19}{- 1}$

Step 3.3

Simplify the right side.

Step 3.3.1.1

Move the negative one from the denominator of $\frac{y}{- 1}$ .

$q = - 1 \cdot y + \frac{- 19}{- 1}$

Step 3.3.1.2

Rewrite $- 1 \cdot y$ as $- y$ .

$q = - y + \frac{- 19}{- 1}$

Step 3.3.1.3

Divide $- 19$ by $- 1$ .

$q = - y + 19$
