Question

Make t the subject of the formula in S=2at/3r-5t​

Answer 1

`t = (3sr)/(2a \ + \ 5s)`

Explanation:

Given expression;

`S = (2at)/(3r - 5t)`

To make "t" the subject of the formula, cross and multiply;

`S(3r - 5t) = 2at\\\\`

open the bracket;

3sr - 5st = 2at

collect like terms together;

3sr = 2at + 5st

Factor out "t" on the right hand side;

3sr = t(2a + 5s)

Finally, make "t" the subject of the formula by dividing both sides by (2a + 5s).

`t = (3sr)/(2a \ + \ 5s)`
