    Answer:

    Step-by-step explanation:

    let tacos be x and burritos be y

    4.5x+7.75y = 519.25

    It says there were twice as many tacos sold as there were burritos sold

    Therefore, y = 2x

    Substituting this in the above equation: 4.5x + 7.75*2x = 519.25

    4.5x+15.5x = 519.25

    x = 519.25/20

    x = 25.9625
