When is the substitution method a better method than graphing for solving a system of linear equations?

  • Algebra -

    If one of the equation is in the form y = ....
    or x = .... , or can easily be changed to one of those forms, I would use substitution

    e.g

    3x + 4y = 36
    y = 2x+3

    definitely use substitution
