The number (x) in: "4 more than twice a number is 703" 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 703.
To solve this, you first write the problem as an algebra equation as follows: 2x + 4 = 703
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 = 703
2x + 4 - 4 = 703 - 4
2x = 699
2x/2 = 699/2
x = 349.5
Answer = 349.5
The answer above is correct, because twice 349.5 is 699, and 4 more than 699 is in fact 703.
