expand (2(-r+45))/5

Solution

expand

\frac{2 ( - r + 45 )}{5}

Solution

- \frac{2 r}{5} + 18

Solution steps

\frac{2 ( - r + 45 )}{5}

Expand

2 (- r + 45) : - 2 r + 90

= \frac{- 2 r + 90}{5}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{- 2 r + 90}{5} = - \frac{2 r}{5} + \frac{90}{5}

= - \frac{2 r}{5} + \frac{90}{5}

Divide the numbers:

\frac{90}{5} = 18

= - \frac{2 r}{5} + 18
