  1. Multiply by the denominator to eliminate it:

    Y/2 + 2 > 7
    Multiply by 2 throughout:
    (Y/2)*2 + 2*2 > 7*2
    Y + 4 > 14
    subtract 4 from both sides:
    Y > 10

    Note:
    If an inequality is multiplied or divided by a negative number, the direction of the inequality must be reversed.
    So in cases like this, watch out that if the denominator is negative, the sign of inequality must be reversed.
