Jeck Share Posted May 5, 2004 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 Link to post Share on other sites
revelized Share Posted May 5, 2004 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. Link to post Share on other sites
anthonycara Share Posted May 6, 2004 dunno cramers thingy but you could do that simultaneous equation with cross-multiplying....8-| Link to post Share on other sites
