Q=3(r+1)/r<br> Make r the subject of the formula
DiKsa [7]

Distribute the 3 to the parentheses.  Q=3r+3/r

Next multiply both sides by r to get rid of the division sign.

Qr=3r+3

Subtract 3r on both sides and you get Qr-3r=3

Since both numbers have an r in it, we can factor out the r

r(Q-3)=3

Then we divide Q-3 on both sides

r=3 / (Q-3)
