Reading A Balance Worksheet Balancing Chemical Equations Help?

Balancing chemical equations help? - reading a balance worksheet

Help! The more I of this worksheet is more confused lol. I am on the following problem set:
____V2O5 ______ + + CASE ______CaO ------> _____V2S5

If someone could help me please, I would be very happy. I read and read more in balance "Chemisty for Dummies" and not helpful lol. If anyone knows a good place to to practice, would be greatly appreciated. Thank you:)

V2O5 + 5CaO + 5CaS → V2S5

Vanadium is now cleared. To take advantage of the 5 atoms of oxygen, will have 5 atoms of calcium. Also need 5 S atoms on the left side.

____V2O5 + + ___5__ CaS __5___CaO ------> _____V2S5

The first is that a single atom of oxygen on the left side. To the other side you have 5 very good, 5 in the CAD.

Secondly, we see that already there is a 5 CaO, calcium not now on the left side, so that adds 5 of the CAS.

And now everything is cleared!

1v2o5 + 5cas -----> 5cao + 1v2s5
