8 more than twice a number is 278




The number (x) in: "8 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 8, you get 278.

To solve this, you first write the problem as an algebra equation as follows: 2x + 8 = 278

Then you solve the equation by subtracting 8 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 8 = 278

2x + 8 - 8 = 278 - 8
2x = 270

2x/2 = 270/2
x = 135

Answer = 135


The answer above is correct, because twice 135 is 270, and 8 more than 270 is in fact 278.
