    Answer:

    x = 2x

    x + 20 = 2x + 20

    And,

    1.5(x + 20) = 2x + 20

    x = 20 i.e. Alexis

    And, Jelani be 40

    Step-by-step explanation:

    Given that

    Jelani has twice as much as Alexis

    And, both can added $20

    Jelani will have 1.5 times as much on his pass on Alexis

    We need to write an equation also the amount does Jelani and Alexis have

    So,

    Let us assume the alexis be x

    And, Jelani be 2x

    Now

    x = 2x

    x + 20 = 2x + 20

    And,

    1.5(x + 20) = 2x + 20

    1.5x + 30 = 2x + 20

    -0.5x = -10

    x = 20 i.e. Alexis

    And, Jelani be 40
