Explanation:
Detailed explanation-1: -Hence, = 3, = 10 is the correct answer.
Detailed explanation-2: -Solution to a System of Linear Equations To verify whether a point is a solution to a system or not, we will either determine whether it is the point of intersection of two lines on a graph or we will determine whether or not the point lies on both lines algebraically.
Detailed explanation-3: -A nxn nonhomogeneous system of linear equations has a unique non-trivial solution if and only if its determinant is non-zero. If this determinant is zero, then the system has either no nontrivial solutions or an infinite number of solutions.
