= 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| =
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 =
x = .1
:
2nd solution
1 - 8x = -.2
-8x = -.2 - 1
-8x = -1.2
multiply both sides by -1
8x = 1.2
x =
x = .15
:
x = .1, .15
