The number (x) in: "6 more than three times a number is 638" 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 6, you get 638.
To solve this, you first write the problem as an algebra equation as follows: 3x + 6 = 638
Then you solve the equation by subtracting 6 from both sides, and then divide both sides by 3. Here is the math to
illustrate better:
3x + 6 = 638
3x + 6 - 6 = 638 - 6
3x = 632
3x/3 = 632/3
x = 210.67
Answer = 210.67
