3 more than twice a number is 278

The number (x) in: "3 more than twice a number is 278" 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 278.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 278

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 = 278

2x + 3 - 3 = 278 - 3
2x = 275

2x/2 = 275/2
x = 137.5

Answer = 137.5

The answer above is correct, because twice 137.5 is 275, and 3 more than 275 is in fact 278.
