9 more than twice a number is 857

The number (x) in: "9 more than twice a number is 857" 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 857.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 857

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 = 857

2x + 9 - 9 = 857 - 9
2x = 848

2x/2 = 848/2
x = 424

Answer = 424

The answer above is correct, because twice 424 is 848, and 9 more than 848 is in fact 857.
