Question

How do you solve `-\frac { - 8} { r + 6} = \frac { 1} { 4}`?

Answer 1

`r=26`

Explanation:

To solve for r, we need to rearrange the equation in such a way that `r` is isolated on one of the sides we can do that by doing the inverse of operations to both sides of the equation.

`-(-8)/(r+6) = 1/4`

`(-1)/1*((-8)/(r+6)) = 1/4`, whether it's `(-1)/1` or `1/-1` doesn't matter.

`8/(r+6) = 1/4`

`8=(1/4) * (r+6)`

`8/(1/4) = r+6`

`8*4 = r+6`

`32 = r+6`

`32 -6 = r`

`r=26`
