The number (x) in: "9 more than three times a number is 770" 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 770.
To solve this, you first write the problem as an algebra equation as follows: 3x + 9 = 770
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 = 770
3x + 9 - 9 = 770 - 9
3x = 761
3x/3 = 761/3
x = 253.67
Answer = 253.67
