The number (x) in: "5 more than twice a number is 619" 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 5, you get 619.
To solve this, you first write the problem as an algebra equation as follows: 2x + 5 = 619
Then you solve the equation by subtracting 5 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 5 = 619
2x + 5 - 5 = 619 - 5
2x = 614
2x/2 = 614/2
x = 307
Answer = 307
The answer above is correct, because twice 307 is 614, and 5 more than 614 is in fact 619.
