Question

How do you solve `-29.5= 5r - 4r`?

Answer 1

`r = -29.5`

Explanation:

Perform the necessary mathematics to solve for `r`:

`-29.5 = (5 - 4)r`

`-29.5 = 1*r`

`-29.5 = r`

Answer 2

`r = -29.5`

Explanation:

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

Since `5r` is the same as

`r+r+r+r+r`

and `4r` is the same as

`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! :)
