    Step-by-step explanation:

    Let Raima’s weight be x .

    Therefore Sia’s weight = x+4.5

    Therefore the equation is ;

    (x) + ( x+ 4.5) = 140

    2x + 4.5 = 140

    2x = 140- 4.5

    2x = 135.5

    x = 67.75

    Therefore Sia’s weight is 67.75 + 4.5

    = 72.25

    Hope it helps.
