**Al B.**, Saturday, January 21, 2012 at 4:16pmSet it up like this;

2x + 3y = 24

x + y = 10 <--use this one to solve for y.

so y = -x + 10 ...

Now substitute (-x + 10) for y in the first equation..so

2x + 3(-x + 10) = 24

2x + (-3x) + 30 = 24

-x + 30 = 24

-x = 24-30 or -6

x = 6, y = 4

so 6 have 2 sails and 4 have 3 sails...
