**Henry**, Thursday, December 16, 2010 at 12:36pmX Rides on merry-go-round.

Y Rides on pirate ships.

Eq1: X + Y = 8 Rides.

Eq2: 0.9X + 0.6Y = 6.30.

Multiply Eq1 by -0.9:

-0.9X - 0.9Y = - 7.20.

0.9X + 0.6Y = 6.30.

Add the Eqs and get:

-0.3Y = -0.9,

Divide both sides by -0.3:

Y - 3 Pirate ship rides.
