Question

Solve for x: −3|2x + 6| = −12

x = 1 and x = 5

x = −1 and x = −5

x = −9 and x = 3

No solution

Answer 1

I think I could solve it, but I want to make sure that I am correct.

Answer 2

@amistre64

Answer 3

its no solution .

Answer 4

Well, I want to see the solving steps.

Answer 5

i agree with @makiadanielle

Answer 6

Can I see how you got that?

Answer 7

just plug in the solutions that are given to you and see if they work is all i can tell you

Answer 8

That's not how you solve it. @amistre64 @jayzdd

Answer 9

that is when it asks you what x eaquals because it gives you ceratin solutions and all you have to do is plug them in

Answer 10

No, I'm pretty sure that you have to divide both sides.

Answer 11

@ParthKohli Could you possibly show me how to do this correctly?

Answer 12

it says that you have to solve for x and there for you have to find what x equals and it gives you a set of choices for you to choose from so there for all you have to do is plug in

Answer 13

-3 |2x+6| = -12

-3, times what, equals -12?

if we cannot determine that it is 4, we can divide off the -3 all the same

so

|2x+6| = 4 , the absolute value of what numbers gives us 4?

|4| = 4
|-4| = 4

so we have 2 cases

2x+6 = 4 or 2x+6 = -4
