Answer: n = 21

Step-by-step explanation: When you're asked to solve for <em>n</em> in an equation, what your really being asked to do is to get <em>x</em> by itself on one side of the equation.

In this problem, since 19 is being added to <em>n</em>, in order to get <em>n</em> by itself, we must subtract 19 from the left side of the equation and when we subtract 19 from the left side of the equation, remember that we must also subtract 19 from the right side of the equation.

So on the left, +19 and -19 cancel eachother out and

on the right, 40 - 19 is 21 so <em>n = 21</em>.

We can check our answer by substituting

a 21 back into the original equation.

So we have (21) + 19 = 40 or 40 = 40.

Vinil7 [7]

Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.

<u>Explanation:</u>

Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:

  1. An even number (eg 2, 4, 6,...), then if they are divided by 2,  the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=<u>1</u>)
  2. An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.
