x=7

Explanation:

Let x represent this mystery number. First we multiply it by 6, than subtract 8, so this can be modeled by the expression 6x-8. We know that this number is equal to 34, so we can rewrite this relationship as an equation:
6x-8=34 Add 8 to both sides:
6x-8+8=34+8 Combine like terms:
6x=42 Divide each side by 6:
(6x)/6=42/6 Simplify:
x=7
