9 more than twice a number is 846

The number (x) in: "9 more than twice a number is 846" 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 846.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 846

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 = 846

2x + 9 - 9 = 846 - 9
2x = 837

2x/2 = 837/2
x = 418.5

Answer = 418.5

The answer above is correct, because twice 418.5 is 837, and 9 more than 837 is in fact 846.
