## anonymous one year ago |3x + 12| = 18 SOLVE

1. Here_to_Help15

What times 3 can equal 18 ?

2. anonymous

6

3. Here_to_Help15

Correct so x=6

4. Here_to_Help15

Wait wait wait

5. anonymous

Thats not even close to one of the options

6. Here_to_Help15

I made a huge mistake lol

7. rock_mit182

8. rock_mit182

you have to solve this : 3x + 12 = 18 and 3x + 12 =-18

9. rock_mit182

because is an absolute value

10. anonymous

2 is one of them right

11. rock_mit182

now solve the second equation

12. anonymous

-10

13. Here_to_Help15

Ok so I'll break it down 3x+12= 18 -12 -12 -------------- 3x=6 $\frac{ 6 }{ 3 } =?$

14. rock_mit182

now you're right, that means how far are you from certain point

15. Here_to_Help15

This is an equation @rock_mit182 the left side is suppose to equal the right side....

16. rock_mit182

and you figure this out by taking what is inside | | = a and what is inside of | | = -a

17. rock_mit182

@Here_to_help15 here we are talking about absolute valu functions

18. rock_mit182

if we have |x| = 3

19. rock_mit182

that means how far you're from zero

20. Here_to_Help15

x does not equal 3!

21. rock_mit182

which could be -3 or 3 units

22. rock_mit182

Im not talking about the last example

23. rock_mit182

by the way, Im just explaining to you what means an absolute value

24. Here_to_Help15

We are both correct....

25. Here_to_Help15

x=2 or -10

26. rock_mit182

of course we do.. exactly

27. rock_mit182

(y)

28. Here_to_Help15

So @brooke_ivy99 which answer choice do you have?
