I'm thinking of a number. When I multiply by 8 and add –1, I get –17. What's my number?
frosja888 [35]

Say that you're thinking of number x

You multiply it by 8, and have 8x

You add -1 (i.e., you subtract 1) and have 8x-1

This equals -17, so you have

8x-1=-17

Add 1 to both sides

8x=-16

Divide both sides by 8:

x=-2

So, you were thinking of -2.
