4 more than twice a number is 790

The number (x) in: "4 more than twice a number is 790" 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 4, you get 790.

To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 790

Then you solve the equation by subtracting 4 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 4 = 790

2x + 4 - 4 = 790 - 4
2x = 786

2x/2 = 786/2
x = 393

Answer = 393

The answer above is correct, because twice 393 is 786, and 4 more than 786 is in fact 790.
