9 more than twice a number is 850

The number (x) in: "9 more than twice a number is 850" 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 850.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 850

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 = 850

2x + 9 - 9 = 850 - 9
2x = 841

2x/2 = 841/2
x = 420.5

Answer = 420.5

The answer above is correct, because twice 420.5 is 841, and 9 more than 841 is in fact 850.
