## avai70178 one year ago How do I solve this absolute value equation? -10-|10n+8|=-78

1. anonymous

-10-(10n+8)=-78 and by switching the signs of everything -[-10-(10n+8)]=-78

2. avai70178

okay but what happens with the negative in front of the absolute value?

3. anonymous

I mean switching the signs of the side with variable in it.

$\large\rm -10-|10n+8|=-78$Should probably add 10 to each side before dealing with the signs that the absolute value gives us :)$\large\rm -|10n+8|=-68$

You make it into parentheses, so just ignore the absolute value Negative times negative makes it positive

6. avai70178

oh okay i see. Thank you so much! :)

7. anonymous

Did you get your first and second solution?

8. avai70178

not yet one sec

9. avai70178

10n+8=+or- 68 right so far?

10. anonymous

Yea that is correct.

11. avai70178

i got n=-38/5 and n=6

12. anonymous

the -68 involves a fraction.

13. anonymous

Yea, I got that too.
