(2/r+3/s+1/t)=1 for t

Question

Solve each formula for the specified variable.  In this case, "t."

Answer 1

me assume that stuf shood be (2/r) +(3/s) +(1/t)=1

(1/t)=1 -(2/r) -(3/s)

.....=(rs/rs) -(2s/rs) -(3r/rs)

(1/t)=(rs -2s -3r)/rs

t=rs/(rs-2x-3r)

Answer 2

To solve for t, multiply through by rst: 2st+3rt+rs=1; 2st+3rt=1-rs; t(2s+3r)=1-rs; t=(1-rs)/(2s+3r).
