I'm not quite certain if your problem is 1%2F8-3%2F4x=1%2F16 or 1%2F8-3%2F4x=1%2F16. I'll solve both



IF IT IS: 1%2F8-3%2F4x=1%2F16
-3%2F4x=1%2F16-1%2F8
-3%2F4x=1%2F16-2%2F16
-3%2F4x=-1%2F16
multiply both sides by -4x%2F3
%28-4x%2F3%29%28-3%2F4x%29=%28-4x%2F3%29%28-1%2F16%29
1=x%2F12
multiply both sides by 12
(12)1=x%2F12(12)
12=x




IF IT IS: 1%2F8-3%2F4x=1%2F16.
2%2F16-%283%29%284%29%2F16x=1%2F16
2%2F16-%2812%2F16%29x=1%2F16
Multiply everything by 16
(16)%282%2F16%29-(16)%2812%2F16%29x=(16)1%2F16
2-12x=1
add 12x to both sides
(2-12x)+12x=(1)+12x
2=1+12x
subtract 1 from both sides
(2)-1=(1+12x)-1
1=12x
Multiply both sides by %281%2F12%29
(1)%281%2F12%29=(12x)%281%2F12%29
%281%2F12%29=x
