Question

Can somepne please help me
Solve for x: −3|x + 7| = −12

iwillrektyou · Answer

I will try to help, but it may take me a bit of time to remember. This wasn't my favorite topic in algebra, but I will try my best.

iwillrektyou · Answer

What are the choices (if any)?

anonymous · Answer

x = −13 and x = −3
 x = 3 and x = −3
 x = 3 and x = 13
 No solution

iwillrektyou · Answer

Every absolute equation has 2 solutions.

pooja195 · Answer

Divide both sides by 3 
−3|x + 7| /3= −12/3
|x+7|=4
We know either x+7=4or x+7=−4

anonymous · Answer

Okay But I think it is no solution

pooja195 · Answer

x+7=4(Possibility 1)
x+7=−4(Possibility 2)

Solve both for x this one does have 2 solutions

iwillrektyou · Answer

For possibility 1, 
x + 7 = 4
    -7     - 7
x = -3

pooja195 · Answer

Can you let the asker solve it please?

anonymous · Answer

So what do you think that it's the second choice?

iwillrektyou · Answer

Solve possibility 2 for x: x+7=−4

anonymous · Answer

So it's the first one becuase x+7+-4 is -13

iwillrektyou · Answer

There are 2 solutions for each absolute value equation. Unless one doesn't have a solution, both are correct.

anonymous · Answer

All the choices have 2 answers in them so I mean is it the first choice

iwillrektyou · Answer

Oh, sorry for misunderstanding. then yes, it is.
