  1. Solving Three Variable Systems of Equations – (Easy)

    Solve the following system of equations by substitution:

    2x+3y+4z=02x + 3y + 4z = 0

    2y+3z=232y + 3z = 23

    z=5z = 5

    1. Solving Three Variable Systems of Equations – (Medium)

      Solve the following system of equations by substitution:

      3x5y+z=03x - 5y + z = 0

      x2yz=0x - 2y - z = 0

      z=2z = -2

      1. Solving Three Variable Systems of Equations – (Hard)

        Solve the following system of equations by substitution:

        15x+7y6z=915x + 7y - 6z = -9

        5x3y+6z=135x - 3y + 6z = 13

        z=4z = 4
