Question

Solve the following:
(a) Find the solution of system of linear equations by using Cramer's Rule
5x + 3y + 7z=4
3x +26y + 2z = 9
7x + 2y +10z = 5​

Answer 1

This can be written as:|A| = 5(260 – 4) – 3(30 – 14) + 7(6 – 182)= 5(256) – 3(16) + 7(176)|A| = 0So, A is singular. Thus, the given system is
