The number (x) in: "3 more than twice a number is 611" 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 611.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 611
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 = 611
2x + 3 - 3 = 611 - 3
2x = 608
2x/2 = 608/2
x = 304
Answer = 304
The answer above is correct, because twice 304 is 608, and 3 more than 608 is in fact 611.
