Calculate the determinant consisting of the coefficients on the variables.  Call that *[tex \LARGE D].  Replace the *[tex \LARGE x]-column of the determinant with the values in the constant column.  Calculate this determinant and call it *[tex \LARGE D_x].  Replace the *[tex \LARGE y] column and calculate *[tex \LARGE D_y] and the *[tex \LARGE z] column and call it *[tex \LARGE D_z], then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ \frac{D_x}{D}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ \frac{D_y}{D}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ z\ =\ \frac{D_z}{D}]

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