Solution

The given system of equations are :2x - 3y = 5x4 - 3y = 1Now, x=4; y = 1 is a solution of above system of equations if it satisfies both simultaneously.Consider the equation 2x - 3y = 5LHS = 2x-3y = 2×4-3×1 = 8 - 3 = 5 = RHSConsider the equation x4 - 3y = 1LHS = x4 - 3y = 44-3×1 = 1 - 3 = -2 RHSHence, 4,1 is not the solution of given system of equations.
