@YanaSidlinskiy @ShadowLegendX @Callisto Please help >.>

nirmalnema · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

Not sure what you guys did there

nirmalnema · Answer

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

@SarahLove<3  do u understand

anonymous · Answer

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

nirmalnema · Answer

yup!!

anonymous · Answer

oooooooooooooooooooooooooooooooooooooooooh

phi · Answer

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

phi · Answer

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

anonymous · Answer

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