    The answer is Z = 2.4

    Step-by-step explanation:

    Let the number be Z

    Z + 4.8 = 3 * Z

    Z + 4.8 = 3Z

    Collect like terms

    4.8 = 3Z - Z

    4.8 = 2Z

    Z = 4.8/2

    Z = 2.4

    The number is 2.4

    Step-by-step explanation:

    Let the number be y

    The sum of the number and 4.8 is written as: y + 4.8

    Three times the number is written as: 3y

    From the question, we were told that the sum of the number and 4.8 is three times the number. This is illustrated as:

    y + 4.8 = 3y

    Collect like terms

    4.8 = 3y - y

    4.8 = 2y

    Divide both side by the coefficient of y i. e 2

    y = 4.8/2

    y = 2.4

    The number is 2.4
