Answer» Given system of linear equations is 3x – 2y = 5 … (1) 2x + y = 7 … (2) Putting x = 3 and y = 2 in equation (2), L.H.S = 2 × 3 + 2 = 6 + 2 = 8 ≠ 7 = R.H.S Hence, x = 3 and y = 2 not satisfying equation (2) which implies that x = 3 and y = 2 is not a solution of the given system of equations. Hence Proved |
