Now kys.

>>8862772
Why are you doing prealgebra on Khan academy

>>8862780
I think it's that same fag who posted something else about how he is trying to learn math but can't understand 8th grade math.

>>8862761
>(((they)))

>>8862773
no its not moron.
x+8=15
then rotate

x
+
8
||
_
~
and the 8 clearly doesnt rotate back correctly so:
X+∞=15
x=15-∞
and take the limit of it
x=-∞
you brainlets should try harder.
