To find the number, we can set up an equation based on the given information.

Let's assume the certain number is "x".

According to the problem, 7 times the certain number (7 * x) is subtracted from 630, resulting in a remainder of thrice the number (3 * x). Mathematically, this can be expressed as:

630 - 7x = 3x

Now, let's solve this equation to find the value of "x".

First, we'll simplify the equation by adding 7x to both sides:

630 = 3x + 7x

Combining similar terms:

630 = 10x

To isolate x, divide both sides by 10:

630/10 = x

Simplifying:

63 = x

Therefore, the certain number is 63.
