X = -7
3 • 7 = 21
-3 • (-7) = 21
If you multiply two negative numbers you’ll end up with a positive. Thus, - 3 (-7) = 21.

Answer:
x = 1/12
1/12 = 0.833
Step-by-step explanation:
to find the value of x
4+ |2-3x| =7
8 - 12x = 7
-12x = 7-8
-12x = -1
x = 1/12
if we write 1/12 in simplest form so
1/12 = 0.833
