Answer:
[tex]\boxed{\bold{r=25}}[/tex]
Step By Step Explanation:
Expand [tex]\bold{8\left(4-r\right): \ 32-8r}[/tex]
Expand [tex]\bold{-6\left(3+r\right): \ -18-6r}[/tex]
Rewrite Equation
[tex]\bold{32-8r=-18-6r}[/tex]
Subtract 32 From Both Sides
[tex]\bold{32-8r-32=-18-6r-32}[/tex]
Simplify
[tex]\bold{-8r=-6r-50}[/tex]
Add 6r To Both Sides
[tex]\bold{-8r+6r=-6r-50+6r}[/tex]
Simplify
[tex]\bold{-2r=-50}[/tex]
Divide Both Sides By -2
[tex]\bold{\frac{-2r}{-2}=\frac{-50}{-2}}[/tex]
Simplify
[tex]\bold{r=25}[/tex]
