    Samuel is 18

    Yvonne is 22

    Step-by-step explanation:

    So let y represent yvonne and s as samuel

    Let's set-up two equations

    y + s = 40

    y + 4 = s

    So since s = y + 4 lets substitute

    y + (y + 4) = 40 which gives us;

    y + y + 4 = 40

    Collect like terms;

    2y + 4 = 40

    Subtract 4 from both sides

    2y = 36

    Divide both sides by 2

    y = 18

    y + 4 = 18 + 4 = 22

    So yvonne is 22 years of age

    40 - 22 = 18

    So Samuel is 18 years of age
