9 more than twice a number is 860

The number (x) in: "9 more than twice a number is 860" 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 860.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 860

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 = 860

2x + 9 - 9 = 860 - 9
2x = 851

2x/2 = 851/2
x = 425.5

Answer = 425.5

The answer above is correct, because twice 425.5 is 851, and 9 more than 851 is in fact 860.
