    Daryl = 9, Malik = 3, Terrance = 14

    Step-by-step explanation:

    We can use letters to represent each brother's name, so

    D + M + T = 26

    3M = D

    D + 5 = T

    then we can plug in the 3M in the third problem for D

    3M + 5 = T

    Then we can go back to the first problem and plug in 3M and (3M + 5)

    3M + M + (3M + 5) = 26

    4M + (3M + 5) = 26

    7M = 21

    M = 3

    plug 3 in for M in the second equation:

    3 x 3 = D

    D=9

    Then go back to the first equation:

    9 + 3 + T = 26

    12 + T = 26

    T = 14

    So T = 14

    D = 9

    and M = 3

    Step-by-step explanation:

    Daryl=D

    Malik=M

    Terrance=T

    D+M+T=26

    D=3M

    T=D+5

    26-5=21

    21=4M+D

    4 (3) + 9=21

    M=3

    D=9

    T=14
