9 more than twice a number is 858

The number (x) in: "9 more than twice a number is 858" 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 858.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 858

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 = 858

2x + 9 - 9 = 858 - 9
2x = 849

2x/2 = 849/2
x = 424.5

Answer = 424.5

The answer above is correct, because twice 424.5 is 849, and 9 more than 849 is in fact 858.
