Answer:
0.8333333333333333 (repeating)
Step-by-step explanation:
Well first the point of this problem is to get "a" by it self so.
-2a = a - 10/4
remove the fraction by multiplying 4 on both sides.
-8a = 4a - 10
now move 4a over to the other side to isolate the 10.
-12a = -10
now divide to get a by it self
-10/-12 = 0.8333333 (repeating)
**Remember a negative divided by a negative is a positive.
