Step 1
Now, let's find the determinants of the matrices obtained by replacing the columns with the constants: $$ \text{det}(A_1) = \begin{vmatrix} 12 & -5 \\ 0 & 8 \end{vmatrix} $$ $$ \text{det}(A_1) = (12)(8) - (-5)(0) = 96 $$ Show more…

solve each system of equations using Cramer's Rule if it is applicable. If Cramer's Rule is not applicable, say so. $$ \left\{\begin{array}{c} {-x+2 y=5} \\ {4 x-8 y=6} \end{array}\right. $$
