(a) Solve the following system of equations by Cramer's rule: 2 x - y =17, 3 x +5 y =6
Solve the following system of equations by Cramer's rule :
$$2 \mathrm{x}-\mathrm{y}=17, \quad 3 \mathrm{x}+5 \mathrm{y}=6$$
Determine the integral value(s) of x for which the matrix A is singular :
$$\mathrm{A}=\left[\begin{array}{ccc}\mathrm{x}+1 & -3 & 4 \\ -5 & \mathrm{x}+2 & 2 \\ 4 & 1 & \mathrm{x}-6\end{array}\right]$$
