3 more than twice a number is 279




The number (x) in: "3 more than twice a number is 279" 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 279.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 279

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 = 279

2x + 3 - 3 = 279 - 3
2x = 276

2x/2 = 276/2
x = 138

Answer = 138


The answer above is correct, because twice 138 is 276, and 3 more than 276 is in fact 279.
