First, substitute the variables for the numbers:
8000=4000%2F%281%2Bt%29

Next, isolate the variable:
8000%281%2Bt%29=4000
[multiply both sides by (1+t)]

%281%2Bt%29=%284000%2F8000%29
[divide both sides by 8000]

t+=+%284000%2F8000%29-1
[subtract 1 from both sides]

Then, simplify:
t+=+%281%2F2%29-1
[simplify the fraction]

t+=+-1%2F2
[subtract the numbers]
