Verified Answer :

so you have to take the 4 to the other side, so it is 24 times by 4 which equals 96

now you have 3r=96
so you divide 96 by 3 to find r

which is, 32 :)

\(24 = \frac{3r}{4}\)

Switch sides :

\(\frac{3}{r} = 24\)

Multiply both sides  by 4 :

\(\frac{3}{4} *4 = 24 * 4\)

\(3 r = 96\)

Divide both sides by 3 :

\(\frac{3r}{3} = \frac{96}{3}\)

\(r = 32\)

hope this helps!
