If eight times a number is subtracted from eleventimes the number, the result is - 9. find the number.

So this question can be representd by

eight times a number, (8x), is subtracted from (-8x) eleven times a number (11x), the result is - 9

so - 8x+11x=-9 or

11x-8x=-9

add like terms

3x=-9

divide both sides by 3

x=-3

The answer is n=3 when n = a number
