having some math trouble and wanted to see if anyone could help

Solve this set of linear equations using Cramer's rule (matrices and determinants).

4X - 5Y = 13

Y - 2X = 1

my bro did it, hes a math major, the coefficient matrix is [[4,-2]^T,[-5,1]^T] and the solution matrix is [13,1]^T where ^T is the transpose of the vector. Using Cramer's rule, then x=18/(-6)=-3 and y=(30)/(-6)=-5.
