I was wondering if someone could double check my work on a test I'm self correcting. Here's the problem, it has to do with Cramer's Rule.
24x + 6y = 11
24x + 60y = 25
I ended up finding the base determinant (D), and then dividing Dx and Dy by D. My answers for Dx and Dy checked out correctly. Here's what I got ultimately.
(.625, .666)
as in, x = .625, y = .666
I think that's correct, but the decimals are throwing me off and I'm not %100 percent sure.

Steve,
that's what I get.
What's wrong with 5/8 and 2/3 ?
It's not always necessary to reduce to decimal values. √2 is exact; 1.414 is not.
