3x + 3y + 6z = 9
2x + 1y + 3z = 7 ⇒ 6x + 6y + 8z = 6
1x + 2y - 1z = -10 6x + 6y + 8z = 6
4z = 12
3x + 3y + 6z = 9 4 4
2x + 1y + 3z = 7 ⇒ 0x + 0y + 4z = 12 z = 3
1x + 2y - 1z = -10 2x + y = -2
2x + (-4) = -2
2x - 4 = -2

2x = 2
2 2
x = 1
(x, y, z) = (1, -4, 3)
<span>We are going to define two equations where b means bagels and m will be muffins,
First equation: 10*b + 4*m = 13
Second equation: 5*b + 8*m = 14
From the second equation, we can isolate b:
b = (14 - 8*m)/5
In the second equation
10*(14 - 8*m)/5 + 4*m = 13
2*(14 - 8*m) + 4*m = 13
28 - 16*m + 4*m = 13
28 -13 = 16*m - 4*m
15 = 12*m
m = 15/12 = 1.25
Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8
So one bagel costs $0.8 and one muffin $1.25</span>

Answer: 0.0072 kilogram
Step-by-step explanation:
Given : The mass of one tablet of ibuprofen =200 mg
Then, the mass of 36 tablets of ibuprofen =
mg
i.e. the mass of 36 tablets of ibuprofen =
mg
We know that 1 kilogram = 1000 grams
and 1 gram = 1000 milligram
Then, 1 kilogram = 
milligrams
Then, 
Now, 
Hence, A commercial package contains 0.0072 kilogram of ibuprofen.
