What in the world this is so ughhh help please

Answer:
-6s = 0
Step-by-step explanation:
Well 8s - 11s = -3s and to move the 3s over you need to minus it so the -3s turns in it -6s. Next you have to move the 6 to the right side by by subtracting so u will get 6 - 6 and that = 0.
so u end with 6s = 0.
