9 more than twice a number is 876

The number (x) in: "9 more than twice a number is 876" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 9, you get 876.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 876

Then you solve the equation by subtracting 9 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 9 = 876

2x + 9 - 9 = 876 - 9
2x = 867

2x/2 = 867/2
x = 433.5

Answer = 433.5

The answer above is correct, because twice 433.5 is 867, and 9 more than 867 is in fact 876.
