Question 213485
If 2t+(s-r)/3= t what is s in terms of r and t?


Step 1.  Let's get rid of denominator by multiplying 3 to both sides of equation:


{{{2t+(s-r)/3= t}}}


{{{2*3*t+(s-r)*3/3= 3*t}}}


{{{6t+(s-r)= 3*t}}}


{{{6t+s-r=3t}}}


Step 2.  Add -6t+r to both sides of equation to get s.


{{{6t+s-r-6t+r=3t-6t+r}}}


{{{s=-3t+r}}}  ANSWER


Step 3.  So s=-3t+r



I hope the above steps were helpful.
