How did you solve it?
jigglypuff314 (jigglypuff314):
plug in 6 for x
so | -4 + 6 | -12
what is -4+6 ?
then that minus 12
OpenStudy (anonymous):
jigglypuff you forget the absolute value signs, they change the value of 4 from negative to positive
OpenStudy (anonymous):
after that the equation is just 4+6-12

so you change -4 to positive then just solve it?
OpenStudy (anonymous):
wait scratch that last bit
jigglypuff314 (jigglypuff314):
not quite,
pemdas so you should do -4+6 first then turn it positive
OpenStudy (anonymous):
I've been on summer break too long, jigglypuff is right about how to solve it
OpenStudy (anonymous):
So its 10 ?

not quite, only whats inside the absolute value signs becomes positive
OpenStudy (anonymous):
so it would be 4+6-12?
jigglypuff314 (jigglypuff314):
it would be -4 + 6 = 2
then 2 - 12 = ?
OpenStudy (anonymous):
-10
jigglypuff314 (jigglypuff314):
-10 is correct ^_^
