  1. since the denominator is the same on both sides, just work with the numerators:

    d+2 = -6
    d = -8

    BZZZT! But thanks for playing. Since the denominator is d+8, d = -8 is not in the domain, because that would cause division by zero.

    Before clearing fractions, be sure to note which values must be excluded from the solution set.
