Given solution:               should be solution.

8p (>/=) -7          8p (>/=) -78p (>/=)-7           8p (>/=) -7       SAME
8p/8 (=) -7/8       8p/8 (>/=) -7/8 DIFFERENT
p (=) -7/8              p (>/=) -7/8    DIFFERENT

The error in the given solution was that the inequality sign > was taken out of the equation. It should not be because the expression is an inequality. p can be any number that is greater than or equal to -7/8. It is not limited to only -7/8.
