9 more than twice a number is 836

The number (x) in: "9 more than twice a number is 836" 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 836.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 836

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 = 836

2x + 9 - 9 = 836 - 9
2x = 827

2x/2 = 827/2
x = 413.5

Answer = 413.5

The answer above is correct, because twice 413.5 is 827, and 9 more than 827 is in fact 836.
