    No reactions so far, so here we go, Wilma !

    What is the problem here? > (bigger than) and < (smaller than) are used similar to =

    15 -1/2x > 6
    15 -1/2x > 6-15
    15 -1/2x > -9
    15- 1/2x > 9
    15-15- x > 18
    So x is bigger than 18

    If you meant with >6 : bigger or equal to 6 :

    15 -1/2x > 6
    15 -1/2x > 6-15
    15 -1/2x > -9
    15- 1/2x > 9
    15-15- x > 18
    So x is equal or bigger than 18

    Very basic algebra !
