    I am Thinking of a number. I multiply it by 3 and add 67. I get the same answer If i multiply by 6 subtract 8.

    Let the number be n. We're given two equal expressions:
    1. 3n + 67
    2. 6n - 8
    Set the expressions equal to each other since they give the same answer:
    3n + 67 = 6n - 8

    We have an equation. Type this equation into our search engine and we get:
    n = 25
