9 more than twice a number is 851

The number (x) in: "9 more than twice a number is 851" 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 851.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 851

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 = 851

2x + 9 - 9 = 851 - 9
2x = 842

2x/2 = 842/2
x = 421

Answer = 421

The answer above is correct, because twice 421 is 842, and 9 more than 842 is in fact 851.
