The number (x) in: "9 more than three times a number is 783" 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 783.
To solve this, you first write the problem as an algebra equation as follows: 3x + 9 = 783
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 = 783
3x + 9 - 9 = 783 - 9
3x = 774
3x/3 = 774/3
x = 258
Answer = 258
