Whoever does paper homework, This is what you do:
Get your homework out. Example: Math or something
Find a word problem and google the exact problem with no lower case at the beginning
When you google that problem, You will most likely find PDFs. Look through the PDFs. One pdf may have only your problem's answer or one pdf may have answers for the whole page! or even a lesson.

Answer:
9 and -3
Step-by-step explanation:
Let the first number be x
Second number = y
x + y = 6
x = 15 - 2y
15 - 2y + y = 6
15 - y = 6
-y = 6 - 15
-y = -9 ( - sign gets cut cuz there is - sign at both the sides)
Therefore, first number = 9
x + y = 6
x = 9 = 6
x = -3
Therefore, second number = -3
Proof:
9 + (-3) = 6

Answer:
The number of bicycle that store sell each month to break even is 13 bikes .
Step-by-step explanation:
Given as :
The operation cost of bicycle store = $2400
The cost of payment by store at average rate = $60 per bike
The average selling price of each bike = s.p = $120 per bike
Let The number of bicycle that store sell each month to break even = n bikes
<u>According to question</u>
The operation cost of bicycle store = (cost of payment by store at average rate + average selling price of each bike ) × number of bicycle that store sell each month to break even
i.e ($60 per bike + $120 per bike) × n bikes = $2400
Or, ($180 per bike) × n bikes = $2400
∴ 180 n = 2400
Or, n = 
i.e n = 13.333 ≈ 13
So, The number of bicycle that store sell each month to break even = n = 13 bikes
Hence, The number of bicycle that store sell each month to break even is 13 bikes . Answer
