\[\left| x+5 \right|=-3/-3=1\]

-3|x+5|+7=4 -3|x+5|=-3 =>|x+5|=1=>x=-4 or x=-6

That looks a bit confusing...I thought I would do distributive property with -3 on x and 5 then add 7 to -15...

if x<0 -(x+5)=1 -x-5=1 x=-6 if x>0 x+5=1 x=-4 x=-4 , -6

Oh you subtracted 7 from both sides than you divided both sides by -3?

the first steps is to get the | x+5 | by itself on the left side add -7 to both sides then divide both sides by -3

once you get | stuff | = 1 (for example) solve two equations stuff = 1 and -stuff = 1 where in your case stuff is x+5: x+5= 1 -(x+5) = 1

\[\left| x + 5 \right| = 1\] Here I would just subtract 5 from both sides yeah?
