    Step-by-step explanation:

    Let the temperature of Phoenix be x

    And temperature of Tucson be y.

    So, the algebraic representation of temperatures in each city can be given as:

    At 6 p. m

    temperature of Phoenix = temperature of Tucson

    i. e x = y

    At 9 p. m

    temperature of Phoenix = x - 2 {temperature in phoenix has dropped 2 degrees}

    temperature of Tucson = y - 4 {temperature in Tucson dropped 4 degrees}

    At 11 p. m

    temperature of Phoenix = (x - 2) - 3 = x - 5 {temperature in phoenix has dropped another 3 degrees}

    temperature of Tucson = (y - 4)
