    The ordered pair that is a solution to the equation (5, 2)

    Step-by-step explanation:

    It is given that,

    2x + 5y = 20

    To find the ordered pairs

    Multiples of 2 are,

    2, 4, 6, 8, 10, 12 ...

    Multiples of 5 are,

    5, 10, 15, 20, ...

    20 can be written as,

    20 = 2x + 5y

    2x is the multiple of 2 and 5y is the multiple of 5

    From the above data we get, 20 = 10 + 10

    2x = 10 then x = 5

    5y = 10 then y = 2

    Therefore the ordered pair that is a solution to the equation (5, 2)
