    More Algebraic Proof

    Use the statement vs reason chart to show that
    5x - 5 = 6 has a solution of x = 11/5.

    What have you been able to do with this? Hint: Look at your thread here for a starting point.

    Re: More Algebraic Proof

    I will list the statements first.

    Statements

    1. 5x - 5 = 6

    2. 5x = 6 + 5

    3. 5x/5 = 11/5

    4. x = 11/5

    Reasons

    1. Given

    2. Addition property of equality

    3. Division property of equality

    4. Proved by statement 3.

    How about this chart?
    Thanks from topsquark

    It is hard to follow considering the separation of the terms using Latex.
