#### Explanation:

Perform the necessary mathematics to solve for

#### Explanation:

Don't let the negative decimal scare you on this one!

Since

#r+r+r+r+r#

and

#r+r+r+r#

this question is as simple as addition and subtraction. If the variable is the same, you can just add or subtract. (Unless there's a different exponent, but don't worry about that at all yet.)

#r+r+r+r+r-r-r-r-r = r#

Therefore,

#r = -29.5#

Hope this helps! :)
