24 times 2 pencils each student is 48 then you divide by 8 to get the number of packages needed which is 8.
I think it’s 2/7=8/28 1/4=7/28
Call the number : x
(1/3)x + 5 = x-6
=> (1/3)x + 5 - (x-6) = 0
=> (1/3)x + 5 - x + 6 = 0
Group (1/3)x with -x, 5 with 6
=> [(1/3)x - x] + (5+6) = 0
=> (-2/3)x + 11 = 0
=> (-2/3)x = -11
=> x = -11 : (-2/3) = 33/2.
Recheck : 1/3 x 33/2 + 5 = 33/6 + 5 = 63/6 = 21/2
33/2 - 21/2 = 12/2 = 6 (21/2 is 6 less than 33/2, satisfied.)
Answer:
D
x >= -8
multiply by 2
-X <= 8
divide by -1
X >=-8 (remember flip sign if multiply by negative)
