7 more than twice a number is 40

The number (x) in: "7 more than twice a number is 40" 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 7, you get 40.

To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 40

Then you solve the equation by subtracting 7 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 7 = 40

2x + 7 - 7 = 40 - 7
2x = 33

2x/2 = 33/2
x = 16.5

Answer = 16.5

The answer above is correct, because twice 16.5 is 33, and 7 more than 33 is in fact 40.
