9 more than twice a number is 79

The number (x) in: "9 more than twice a number is 79" 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 79.

To solve this, you first write the problem as an algebra equation as follows: 2x + 9 = 79

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 = 79

2x + 9 - 9 = 79 - 9
2x = 70

2x/2 = 70/2
x = 35

Answer = 35

The answer above is correct, because twice 35 is 70, and 9 more than 70 is in fact 79.
