3 more than twice a number is 308

The number (x) in: "3 more than twice a number is 308" 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 3, you get 308.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 308

Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 3 = 308

2x + 3 - 3 = 308 - 3
2x = 305

2x/2 = 305/2
x = 152.5

Answer = 152.5

The answer above is correct, because twice 152.5 is 305, and 3 more than 305 is in fact 308.
