KatRina [158]

Answer:

The number is -6.

Step-by-step explanation:

3(-6) + 12 = -6

-18 + 12 = -6

-6 = -6

12. $\frac{r-3}{-4-(-8)} = -5$
$\frac{r-3}{4} = -5$
r - 3 = 4(-5)
r - 3 = -20
r = -20 + 3
r = -17

13. $\frac{r-2}{-2-5} = \frac{5}{6}$
$\frac{r-2}{-7} = \frac{5}{6}$
6(r - 2) = -7(5)
6r - 12 = -35
6r = -35 + 12
6r = - 23
r = $\frac{-23}{6}$
