what happens when you divide both sides by -5?
OpenStudy (anonymous):
I got -2 @jim_thompson5910
OpenStudy (freckles):
Can distance be negative?
OpenStudy (freckles):
Does anything have a distance of -2 from 0?
jimthompson5910 (jim_thompson5910):
correct, you should get -2 on the right side. Do you understand what freckles is asking? or no?

no
jimthompson5910 (jim_thompson5910):
absolute value represents distance
for example, |-3| = 3 means that -3 is three units away from 0
if we said |x| = 2, then the answers are x = -2 or x = 2 because each number is two units away from 0.
Notice how the distance is never negative
jimthompson5910 (jim_thompson5910):
so saying |x + 1| = -2 is impossible
therefore, there are no solutions to this equation or the original equation
jimthompson5910 (jim_thompson5910):
there are no values of x that will make |x + 1| = -2 true
there are no values of x that will make -5|x + 1| = 10 true

oh okay, thank you so much! (:
