    Answer:

    24 and 6 are the 2 numbers

    Step-by-step explanation:

    let the 2 numbers be x and y , then

    x + y = 30 → (1)

    y = 4x → (2) [ one number is 4 times the other ]

    Substitute y = 4x into (1)

    x + 4x = 30

    5x = 30 ( divide both sides by 5 )

    x = 6

    Substitute x = 6 into (2)

    y = 4 × 6 = 24

    The 2 numbers are 24 and 6
