1. BabyBoy1

x=6/5

2. BabyBoy1

check for yourself its right hun !

3. angelleighh

I need the work for the problem too

4. BabyBoy1

ohhh ok

5. BabyBoy1

x=39/37 = x=6/5

6. angelleighh

How do you get that answer?

7. BabyBoy1

My calculator :]

8. angelleighh

But, what are the steps? Haha

9. BabyBoy1

Oh lol idk my calculator just solved it . Sorry :/

10. angelleighh

Well, i have no clue how to do it.

two solutions 6/5 and 39/37 1 sec writting how to solve :x

12. dumbcow

always get the absolute value part alone on 1 side first |9-8x| = (2x+3)/9 then split it into 2 cases, pos and neg --> 9-8x = (2x+3)/9 and --> 9-8x = -(2x+3)/9 solve each equation for x

13. nphuongsun93

|9-8x| -> (9-8x) and (8x-9) 9 (9 - 8x) = 2x + 3 81 - 72x = 2x + 3 78 = 74x x = 78/74 = 39/37 9 (8x - 9) = 2x + 3 72x - 81 = 2x + 3 70x = 84 x = 84/70 = 6/5

THANK YOU GUYS FOR EXPLAINING IT =]

15. angelleighh

Thanks so muchh!

16. lgbasallote
