    Ok, We would first want to distribute on the left side of the equation. Could you do that for me?

    That isn't work, that is using a guess and check technique. @goformit100 used an algebraic method that I had planned on guiding the asker through.

    Guess and check works fine with multiple choice.

    One last thing before I go, Guess and check may work fine for multiple choice. However, to apply this to later problems that do not offer choices for answers; you need to know how to solve the problems algebraically.
