Question

Solve for t in terms of the other variables.
k= 3tm + rs

Answer 1

`t=(k-rs)/(3m)`

Explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs {subtract rs from both sides}

k - rs = 3tm {divide both sides by (3m)}

`(k-rs)/(3m)=t` {swap sides}

`t=(k-rs)/(3m)` m≠0

{m must be ≠0 because you cannot divide by 0. There is no t for m=0}
