Hi there! The answer is k = 16
To find our answer we only need to collect the terms. In other words: we need to subtract all the values of k.
Example:

If you don't get this, you can try to understand it by using a story: in a cage, there are 18 koalas, 11 of them leave. How many are left?
18 koalas - 11 koalas = 7 koalas
18 k - 11 k = 7 k
Now we keep doing this again and again to find our final answer:

~Hope this helps you!

Almonds in hypothetical bag of which we cannot see
Answer:
y = 3 + 12x - - - (1)
y = 9 + 10x - - - (2)
3 albums
$39
Step-by-step explanation:
Let number of download = x
Given :
I-moon :
Initial joining fee = $3
Cost per download = $12
Hence,
y = 3 + 12x - - - (1)
I - Toons :
Initial joining fee = $9
Cost per download = $10
y = 9 + 10x - - - (2)
For cost to be the same ;
Equate (1) and (2)
3 + 12x = 9 + 10x
Collect like terms
3 - 9 = 10x - 12x
-6 = - 2x
x = 3
It will take 3 albums
Cost :
3 + 12(3)
3 + 36 = 39
Answer:
6th Day = 62
12th Day = 122
15th Day = 152
Step-by-step explanation:
y = 10x + 2
y = 10(6) + 2
y = 60 + 2
y = 62
y = 10x + 2
y = 10(12) + 2
y = 120 + 2
y = 122
y = 10x + 2
y = 10(15) + 2
y = 150 + 2
y = 152
