If you would like to know what number does q equal, you can calculate this using the following steps:

- 3/4 * q = 12     /*(- 4/3)
q = 12 * (- 4/3)
q = - 12 * 4 / 3
q = - 16

The correct result would be - 16.

-3/4q = 12

proportion = a/b = cd  where: ad = bc
a = -3 ; b = 4q ; c = 12 ; d = 1

do cross multiplication:

-3/4q = 12/1
-3*1 = 12*4q
-3 = 48q
q = -3/48 or - 0.0625

to check:
-3/4q = 12
-3/4(-0.0625) = 12
-3/-0.25 = 12
12 = 12
