9 more than twice a number is 887

The number (x) in: "9 more than twice a number is 887" 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 887.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 887

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 = 887

2x + 9 - 9 = 887 - 9
2x = 878

2x/2 = 878/2
x = 439

Answer = 439

The answer above is correct, because twice 439 is 878, and 9 more than 878 is in fact 887.
