Question

Solve for t in the formula above to obtain a formula expressing tas a function of V.V= 14.5 – 1.3t t=

Answer 1

Given the equation:

$V=14.5-1.3t$

We want to make t the subject of formula;

firstly, let us subtract 14.5 from both sides.

$\begin{gathered} V=14.5-1.3t \\ V-14.5=14.5-14.5-1.3t \\ V-14.5=-1.3t \\ -1.3t=V-14.5 \end{gathered}$

Then let's divide both sides by -1.3;

$\begin{gathered} \frac{-1.3t}{-1.3}=\frac{V-14.5}{-1.3} \\ t=\frac{-V+14.5}{1.3} \end{gathered}$
