    Let's named variables as M, J and R

    The equation is M+J+R=74

    We will represent M with J = > M=J+6 and R=2J

    when we replace in the equation we get

    J+6+J+2J=74 = > 4J=74-6 = > 4J=68 = > J=68/4 = 17

    J=17 = > M=6+17 = > M=23 and R=2 * 17 = > R=34

    Final answer is

    Juan served 17 orders

    Melissa served 23 orders and

    Rafael served 34 orders

    Good luck!
