    Answer:

    Assuming the formula below, the answer is:

          r=\dfrac{12s}{12+t}

    Explanation:

    I can teach you how to make r the subject of a formula, with an example.

    Other similar question asks to make r the subject of this formula:

             t=\dfrac{12(s-r)}{r}

    1. Apply multiplication property of the equalities: muliply both sides of the equality by r

           t\times r=12(s-r)

    2. Apply distributive property on the right side

          t\cdot r=12s-12r

    3. Addition property: ad 12r to both sides

           t\cdot r+12r=12s

    4. Common factor r on the left side

            r(12+t)=12s

    5. Division property of equalities: divide both sides by 12 + t

            r=\dfrac{12s}{12+t}
