Your solution My solution
8p (>/=) -7 8p >/= -7
8p/8 (=) -7/8 <span>8p/8 </span>>/= -7/8
<span>p (=) -7/8 </span><span>p </span>>/= <span> -7/8</span>
The last two equation only has the equal "=" sign. The greater than ">" sign was removed.
Greater than ">" sign should not be removed because the expression is an inequality.
Inequality expressions deal with numerous numbers that can make the inequality true.
Putting only an equal sign will limit the number option into 1. It will only make half of the inequality true. P = -7/8 but it is not > -7/8.
