The number (x) in: "3 more than three times a number is 837" 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 3, you get 837.
To solve this, you first write the problem as an algebra equation as follows: 3x + 3 = 837
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 3 = 837
3x + 3 - 3 = 837 - 3
3x = 834
3x/3 = 834/3
x = 278
Answer = 278
