The number (x) in: "9 more than three times a number is 786" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by three (same as three times) and then add 9, you get 786.
To solve this, you first write the problem as an algebra equation as follows: 3x + 9 = 786
Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 9 = 786
3x + 9 - 9 = 786 - 9
3x = 777
3x/3 = 777/3
x = 259
Answer = 259
