Question 947010
Simple number properties and inverse operations chosen to isolate R.


Simple multiplication by 1:
{{{1/R=(1/S)(T/T)+(1/T)(S/S)}}}


Simple fraction skills:
{{{1/R=(T-S)/(ST)}}}


If you really want, multiply both sides by R:
{{{(1/R)*R=R(T-S)/(ST)}}}


{{{1=R(T-S)/(ST)}}}


Multiply both sides by {{{(ST)/(T-S)}}}:

{{{highlight((ST)/(T-S)=R)}}}
