(t-4)-5= 0
-5t+20= 0
-5 t= -20
-t = -4
t = 4

Add 5 to both sides, so you can isolate the absolute value:
|t-4|=5
Now, remember that absolute value ( | | ) means that the quantity inside could be either positive or negative, so make the 5 both positive or negative, and the next step looks exactly like this:
t-4=5 or t-4=-5
Solve both equations to get:
t=9 or t=-9
for an answer. You're welcome!!!

To solve |t-4|=5, you need to solve t-4=5, and then t-4=-5, so you'll get two solutions. This is because |5|=|-5|=5.

| t-4 | = -5
and
| t-4 | = 5
t = -1
and
t = 9
