  1. the easy one first:
    2(x+7)-4>5(x-3)
    2x + 14 - 4 > 5x - 15
    -3x > -25
    x < 25/3

    for the 1st, I don't know why you put brackets around the left side, since it serves no purpose

    did you mean 2/(5x) > 7
    or
    (2/5)x > 7

    I will assume the last case:
    mulitply both sides by 5
    2x > 35
    x > 35/2
