    m + mrt = r

    r(1 - mt) = m

    r = m/(1 - mt)

    (1) If m = (r/1) + rt, than:

    => m = r + rt

    => m = r(1+t)

    => r = m/(1+t) <<<

    (2) If m = r/(1+rt), than:

    => m(1+rt) = r

    => m + mrt = r

    => r - mrt = m

    => r(1-mt) = m

    => r = m/(1-mt) <<<

    do you mean m=r/(1+rt)

    to solve for r , you need to express r in terms of everything else,in other words, isolate r on one side of the equality

    multiply both sides of the equality by (1+rt)

    m(1+rt) = r expand the brackets....

    m + rtm =r subtract rtm from both sides...

    m = r-rtm take r out as a common factor...

    m = r(1-tm) divide both sides by (1-tm)

    we solve for r

    r = m/(1-tm)

    m=r/1+rt; r/1=>r

    m=r(1+t)

    m/(1+t)=r

    m...............r

    ***....=....*******.............Cross Multiply

    1............1 + rt

    r*1 = m*(1 + rt)

    r = m + mrt

    r - mrt = m

    r(1 - mt) = m

    r = m / (1 - mt).............ANSWER
