Question 504360: 1/(1-8x)= 5
the parenthesis are not supposed to be parenthesis, they are supposed to be absolute value signs
I know i have to isolate the absolute value but im confused as exactally which method to use in order to do that.....not sure if i should switch to a neg. or multiply by 1/5 im bogged....and having extreme brain farts. SEMPER!!

You can put this solution on YOUR website!
1%2F%281-8x%29= 5
multiply both sides by|1-8x|, results:
1 = 5|1 - 8x|
Rewrite it to
5|1 - 8x| = 1
divide both sides by 5
|1 - 8x| = 1%2F5
or
|1 - 8x| = .2
Remove the abs
1st solution
1 - 8x = .2
-8x = .2 - 1
-8x = -.8
Multiply both sides by -1
8x = .8
x = .8%2F8
x = .1
:
2nd solution
1 - 8x = -.2
-8x = -.2 - 1
-8x = -1.2
multiply both sides by -1
8x = 1.2
x = 1.2%2F8
x = .15
:
x = .1, .15
