    [a = b + 5x/8]8

    8a = 8b + 5x

    8a - 8b = 5x

    ........8a - 8b........... 8(a - b)

    x = -------------- or  ----------------- answer//

    ..........5  .................... 5

    a = b + 5x/8

    a - b = 5x/8

    8(a - b)/5 = x

    a=b+5x/8

    a-b=5x/8

    8(a-b)=5x

    (8(ab))/5=x<

    (8/5)*ab=x<

    1.6ab=x<

    It is: x = 8(a-b)/5 => (8a-8b)/5 or x = 1.6a-1.6b

    as written:

    a = b + 5x/8

    Subtract b from both sides:

    a - b = 5x/8

    Then multiply both halves by (8/5):

    (8/5)(a - b) = x

    a = b + 5x/8

    8a = 8b + 5x

    5x = 8a - 8b

    x = (8/5)(a-b) ...........ANS

    you really have to learn simple algebra

    a = b + 5x/8

    8a = 8b + 5x

    5x = 8a – 8b

    x = (8a – 8b) / 5

    or

    x = (8/5)(a – b)
