The number (x) in: "3 more than three times a number is 840" 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 840.
To solve this, you first write the problem as an algebra equation as follows: 3x + 3 = 840
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 = 840
3x + 3 - 3 = 840 - 3
3x = 837
3x/3 = 837/3
x = 279
Answer = 279
