    Answer:

    13/19

    Step-by-step explanation:

    (5*/3)-4=2*/5

    (5*/3)-(2*/5)=4

    (25x-6x)/15=4

    19x=15*4

    x=60/19

    hence

    2x-7

    2(60/19)-7

    (120/19)-7

    (120-133)/19

    13/19

    Answer:

    5x/3 – 4 = 2x/5


    5x/3 – 2x/5 = 4


    Taking LCM,


    (25x – 6x)/15 = 4


    25x – 6x = 60


    19x = 60


    x = 60/19.


    ——————————


    2x – 7


    = 2(60/19) – 7


    = 120/19 – 7


    = 6.315… – 7


    = -0.684….
