B Simultaneous linear equations

  1. Jun 10, 2017 #1
    The term simultaneous in simultaneous linear equations does not make sense to me? Would you explain the what simultaneous mean there?

    Example: "We have all solved simultaneous linear equations - for example,

    2x + y = 4
    x - 2y = -3 "

    Thank you.

    It means more than one equation that must be satisfied by the same solution: in this case, the same values of ##x## and ##y## must satisfy both equations.
