Answer 2

the number
`\( x \)` is -11.

To find the number
`\( x \)` such that the difference of 2 times \( x \) and 8 is -30, we set up and solve the equation:

`\[ 2x - 8 = -30 \]`

Adding 8 to both sides of the equation to isolate the term with \( x \) on one side gives us:

`\[ 2x = -30 + 8 \]`

`\[ 2x = -22 \]`

Dividing both sides by 2 to solve for
`\( x \)` gives us:

`\[ x = (-22)/(2) \]`

`\[ x = -11 \]`

So the number
`\( x \)` is -11.
