can someone explain step by step to do math problems for to solve the system ill use an example 7x3y=-2 -7x-7x=14

  • math -

    correct the typo in 7x3y=-2

    type each equation in a new line, so we tell where one ends and the next one begins.

    this is worse than before, now I have to read it as

    21xy = -2
    -49x^2 = 14

    it can't be that, since the second equation clearly has no real solution.

    I have a feeling you meant to type

    7x + 3y = -2
    -7x + 7y = 14

    but until you clarify the equation, there is no point in working it out.

    7x + 3y = -2
    -7x + 7y = 14
