Solve for x: -3|x + 7| = -12

 x = 5 over 3, x = −19 over 3

 x = −3, x = −11

 x = −3, x = 11

 No solution

Any attempt?

kaliyah0524 · Answer

Not sure where to start @Callisto

unklerhaukus · Answer

-3|x + 7| = -12

start by dividing both sides by -3

kaliyah0524 · Answer

So its C or B... How do i solve it to get either the 11 or -11 @UnkleRhaukus

unklerhaukus · Answer

huh?
what did you get when you divided?

kaliyah0524 · Answer

|x+7|=4

unklerhaukus · Answer

good, so now you have two cases

I. 
    (x+7) = 4 


II.
  -(x+7)=4 



take it one at a time

unklerhaukus · Answer

I. 
    x+7 = 4 


now take away seven . . .

kaliyah0524 · Answer

-3.. I got tht already

unklerhaukus · Answer

ok thats one solution

now the second one 

II.
  -(x+7) = 4 
              =                     ( divide both sides by -1 )
              =                     ( take away seven  . . .     )

kaliyah0524 · Answer

-11. Thnks (:

unklerhaukus · Answer

-(x+7) = 4 
    x+7  = -4                ( dividing both sides by -1 )
     x      = -4-7           ( taking away seven  . . .     )
     x      = -11              √
