    I will do one, and will be happy to critique your work on the others. THe only thing different about these and ordinary equations is that when you divide or multiply be a negative number, the inequality reverses.

    5) 3x-11>-x+17
    add x to each side, add 11 to each side.
    4x>28
    divide both sides by 4
    x>7
