Question

Jika p=-2, q = 3, dan r = -4,maka hasil dari -6p : q + 3(3r - 2q) adalah....a.-36
b.-50
c.-86
d.-122

Answer 1

 p=-2, q = 3, dan r = -4
-6p : q + 3(3r - 2q)= -6 (-2)  :  3  +  3 ( 3 (-4)  - 2 (3) )
= 12 : 3 + 3 ( -12 - 6 )
= 4 + 3 (-18 )
= 4 + (- 54)
= 4 - 54
= -50

Answer 2

-6p : q + 3(3r - 2q)
= (-2 x (-6)) : 3 + 3(3 x (-4) - 2 x 3)
= 12 : 3 + 3(-12 - 6)
= 12 : 3 + (-54)
= 4 + (-54)
= -50  (b)
