9 more than twice a number is 834

The number (x) in: "9 more than twice a number is 834" 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 834.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 834

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 = 834

2x + 9 - 9 = 834 - 9
2x = 825

2x/2 = 825/2
x = 412.5

Answer = 412.5

The answer above is correct, because twice 412.5 is 825, and 9 more than 825 is in fact 834.
