The number (x) in: "5 more than three times a number is 515" 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 5, you get 515.
To solve this, you first write the problem as an algebra equation as follows: 3x + 5 = 515
Then you solve the equation by subtracting 5 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 5 = 515
3x + 5 - 5 = 515 - 5
3x = 510
3x/3 = 510/3
x = 170
Answer = 170
