Subtracting what number from 30 gives 8?

To determine which number, when subtracted from 30, results in 8, we can set up the equation:

30 - x = 8

Here, x represents the number we are looking for. To solve for x, we rearrange the equation as follows:

x = 30 - 8

When we calculate this, we find:

x = 22

This shows that subtracting 22 from 30 gives us 8, which confirms that the correct answer is indeed the number 22. This approach effectively highlights the arithmetic involved in solving for the unknown, providing clarity on how the solution is reached.
