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

=color(blue)(3

#### Explanation:

(3x+12) / (x+4

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

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

The expression now becomes:

$\frac{3 x + 12}{x + 4} = \frac{\textcolor{b l u e}{3 \left(x + 4\right)}}{x + 4}$

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

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

=color(blue)(3
