    Answer: Jordan worked for 10 hours and Sydney worked for 6 hours.

    Step-by-step explanation:

    Let x represent the number of hours

    that Jordan worked.

    Let x represent the number of hours that Sydney worked.

    Jordan can iron 20 shirts per hour, and Sydney can iron 25 shirts per hour. They ironed 350 shirts between them. It means that

    20x + 25y = 350- – – – – – – – – – – 1

    Jordan worked 4 more hours than Sydney. It means that

    x = y + 4

    Substituting x = y + 4 into equation 1, it becomes

    20(y + 4) + 25y = 350

    20y + 80 + 25y = 350

    20y + 25y = 350 – 80

    45y = 270

    y = 270/45

    y = 6

    x = y + 4 = 6 + 4

    x = 10
