9 more than twice a number is 877

The number (x) in: "9 more than twice a number is 877" 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 877.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 877

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 = 877

2x + 9 - 9 = 877 - 9
2x = 868

2x/2 = 868/2
x = 434

Answer = 434

The answer above is correct, because twice 434 is 868, and 9 more than 868 is in fact 877.
