Hi, there.

_____

First off, distribute 3 through parentheses.


\boldsymbol{3(r-7)=24}\\\boldsymbol{3r-21=24}

Next, add 21 to both sides.


\boldsymbol{3r=45}

Divide both sides by 3.


\boldsymbol{r=15}

Hope the answer - and explanation - made sense,

happy studying.

3(r-7)=24

Multiply bracket out

3r - 21 = 24

+21

3r. = 45

÷ 3

r = 15

Hope this helps!
