Answer: x = 8.1
Explanation:
Let the number be x.
6 times the number = 6x
When 3.9 is added to 6 times a number, the result is 52.5. This means that
3.9 + 6x = 52.5
Subtracting 3.9 from both sides, we have
3.9 - 3.9 + 6x = 52.5 - 3.9
6x = 48.6
Dividing both sides by 6, we have
6x/6 = 48.6/6
x = 8.1
The number is 8.1
