I'm going to assume that you can evaluate a 2X2 determinant. If you can't, write back and we'll talk about that.

(A 2X2 matrix consisting of the coefficients)

(The 2X2 matrix from above, replacing the x coefficients with the constant values)

(The 2X2 matrix from above, replacing the y coefficients with the constant values)

Cramer's Rule says, and , so and
