Question

3/t = 5/t-7

Answer 1

Alright, you cross multiply if the fractions are equal in order to solve for t.

\(\Large \color{purple}{\rightarrow 3(t - 7) = 5t }\)
\(\Large \color{purple}{\rightarrow 3t - 21 = 5t }\)
\(\Large \color{purple}{\rightarrow 5t - 3t = -21 }\)
\(\Large \color{purple}{\rightarrow 2t = -21}\)
\(\Large \color{purple}{\rightarrow t = -10.5 }\)

Answer 2

Is (t - 7) the denominator?
