Try solving the above first for |x|
OpenStudy (anonymous):
idk how thats why i put it on here
OpenStudy (anonymous):
how?
myininaya (myininaya):
ok i didn't know you didn't know how to isolate |x|
myininaya (myininaya):
so that means if we had the equation 15+x=26
you wouldn't know how to solve that for x right?

0?
myininaya (myininaya):
yes a+(-a) is 0
myininaya (myininaya):
so if we had the equation a+|x|=b
and I wanted to solve it I would first +(-a) on both sides
so I would have
a+(-a)+|x|=b+(-a)
0+|x|=b+(-a)
but 0+|x| is |x|
|x|=b+(-a) <--- so we have solve a+|x|=b for |x|
myininaya (myininaya):
can you do that with your problem solve it for |x| now?
myininaya (myininaya):
hint the +(-15) on both sides
