#### Explanation:

We can simply apply the algebraic techniques of balancing (Golden Rule of Algebra).

$s t + 3 t = 6$

we must isolate the variable $s$ by transposing all other variables to other side of the equation.

$s t = 6 - 3 t$

$s = \frac{6 - 3 t}{t}$

$s = \frac{6 - 3 \cancel{t}}{\cancel{t}}$

$s = 3$
