why did you re-write the denominator as "15x - 5" as opposed to + 5??

[@RobbyBoy167]

yeah it seems he made a mistake

[@wolfhawk9876]

Yea this just made me more confused, is the answer the same if you fix it?

[@suras8984]

Wolf Hawk Yea he lost me after that.... Im not sure if its a mistake or a necessary step. And if its necessary an explanation would be nice. It would be nice if he read the comments so he could clarify.

[@tmwbatman1160]

Either way (-5 or +5) same result.

[@shoberino3898]

Just a mistake. The process is still the same, nothing to be confused about

[@CATboss001]
