Question

Describe and correct the error in finding the solution to 8p (>/=) -7

8p (>/=)-7
8p/8 (=) -7/8
p (=) -7/8

Answer 1

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.
