    If i triple the number then subtract 7 the answer is 2. What is the number

    Let the number be x.

    Triple the number:
    3x

    Subtract 7
    3x - 7

    The answer is 2 means we set:
    3x - 7 = 2

    This is our algebraic expression. To solve this, we type this problem into the search engine and get x = 3.
