Question

solve for s.
$r = \frac{2s + 3}{t}$
$s = \frac{r? - 3}{\square}$

Explanation:

Step1: Multiply both sides by t

$r \times t = \frac{2s + 3}{t} \times t$
$rt = 2s + 3$

Step2: Isolate the term with s

$rt - 3 = 2s$

Step3: Solve for s

$s = \frac{rt - 3}{2}$

Answer:

The missing value in the green box is $\boldsymbol{t}$, and the missing value in the beige box is $\boldsymbol{2}$. The fully solved formula is $s = \frac{rt - 3}{2}$
