1 more than twice a number is 289

The number (x) in: "1 more than twice a number is 289" 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 1, you get 289.

To solve this, you first write the problem as an algebra equation as follows: 2x + 1 = 289

Then you solve the equation by subtracting 1 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 1 = 289

2x + 1 - 1 = 289 - 1
2x = 288

2x/2 = 288/2
x = 144

Answer = 144

The answer above is correct, because twice 144 is 288, and 1 more than 288 is in fact 289.
