$=color(blue)(3$

$(3x+12) / (x+4$

The expression $3x+12$ has $3$ common between both the terms:

So,
$3x+12 = color(blue)(3(x+4)$

The expression now becomes:

$(3x+12) / (x+4 )= color(blue)(3(x+4))/(x+4)$

$x+4$ is common to both the numerator and denominator here.

$= color(blue)(3(cancel(x+4)))/(cancel(x+4)$

$=color(blue)(3$

How do you simplify (3x+12)/(x+4)(3x+12)/(x+4)?
