$3$ $color(blue)(3)$

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

$s t + 3 t = 6$ $st + 3t = 6$

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

$s t = 6 - 3 t$ $st= 6-3t$

$s = \frac{6 - 3 t}{t}$ $s = (6-3t)/t$

$s =(6-3cancelt)/cancelt$

$s = 3$
