@LuckyStarlVl I think you're just going to divide it by -1

5-|x+3|-3=7

-lx+3l = 7+3-5

-lx+3l = 5

lx+3l = -5

Then you can start solving:

x+3=-5 and x+3=5

:D

Could you please do examples like |2x-1l + lx-2l = 5 - lx+1l ? That would be very helpful! :D

What if there's a negative sign outside the absolute value, like 5-|x+3|-3=7 D:

wouldn't the answer then be no solution because you can't go a negative distance?

@rockyuuz There is a forum. The videos are the thread topic and the comment section is the forum. It works perfect so far.
