9 more than twice a number is 842

The number (x) in: "9 more than twice a number is 842" 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 842.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 842

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 = 842

2x + 9 - 9 = 842 - 9
2x = 833

2x/2 = 833/2
x = 416.5

Answer = 416.5

The answer above is correct, because twice 416.5 is 833, and 9 more than 833 is in fact 842.
