In the literal equation 7z - 3x = 18 Z - 5x + 1 How do I know which one to flip?

    What i mean by flip is in the equation x - y = 4 4y - x = 14 I flip the x - y = 4 to x = 4 + y

    Sorry equation is supposed to be 7z - 3x = 18 Z - 5x = 1

    look z has got coefficient 1, so its easy to handle with that

    you flip which ever one you want; make a choice and stick with it

    So it is a matter of choice, it doesn't matter which one you flip? You will get the same answer out of both?

    it doesnt matter which variable you start with, or which equation .... just do what you think is easiest for you to solve with ...

    that will lead to fractional value, a bot hard..nothing wrong with it anyways

    She came up with 7z = 18 + 3x z + 18 + 3x / 7 / = fraction

    and that is completely usable ..... but does it have to be done that way? no

    and then it was 2(18 + 3x / 7) - 5x = 1

    since z=z=z=z.... it doesnt matter how you 'solve' for z; its gonna retain the same value thruout the process

    To avoid fractions (which I hate) I would flip the 2z - 5x = 1

    fractions can be cleared tho; just multiply it all by the bottom number
