Answer:

-2\frac{1}{10}

Step-by-step explanation:

The expression given can be rewritten as:

-\frac {4}{10}-x-\frac {9}{10}

Because +(-n) is just -n. Then, combine like terms to get:

-\frac{13}{10}-x

Substitute \frac{4}{5} for x to get:

-\frac{13}{10}-\frac{4}{5}

Which can be rewritten as:

-\frac{13}{10}-\frac{8}{10}

Which is:

-\frac{21}{10}. -2\frac{1}{10} as a mixed number

Hope this helps :)
