Let's call the number "x".
The sentence "7 times a number is 30 greater than the sum of twice the number and 5" can be written as:
7x = 2x + 5 + 30
Simplifying the right side of the equation:
7x = 2x + 35
Subtracting 2x from both sides:
5x = 35
Dividing both sides by 5:
x = 7
Therefore, the number is 7.
