For the matrix
The determinant is
Given the system
First calculate the determinant of the coefficient matrix:
Then replace the first column with the constant values and calculate 
Then replace the second column with the constant values and calculate 
Finally, solve for 
and 
For your problem:
\left(\frac{5}{2}\right)\ -\ \left(-\frac{1}{4}\right)\left(-\frac{5}{2}\right)\ =\ \frac{5}{3}\ -\ \frac{5}{8}\ =\ \frac{25}{24})
I'll let you do the rest of the arithmetic.

My calculator said it, I believe it, that settles it
