Answer» 3 = 0L.H.S. = X + 3By putting x = 3,L.H.S. = 3 + 3 = 6 ≠ R.H.S.∴ No, the equation is not satisfied.(ii) x + 3 = 0L.H.S. = x + 3By putting x = 0,L.H.S. = 0 + 3 = 3 ≠ R.H.S.∴ No, the equation is not satisfied.(iii) x + 3 = 0L.H.S. = x + 3By putting x = −3,L.H.S. = − 3 + 3 = 0 = R.H.S.∴ Yes, the equation is satisfied.(IV) x − 7 = 1L.H.S. = x − 7By putting x = 7,L.H.S. = 7 − 7 = 0 ≠ R.H.S.∴ No, the equation is not satisfied.(v) x − 7 = 1L.H.S. = x − 7By putting x = 8,L.H.S. = 8 − 7 = 1 = R.H.S.∴ Yes, the equation is satisfied.(vi) 5x = 25L.H.S. = 5XBY putting x = 0,L.H.S. = 5 × 0 = 0 ≠ R.H.S.∴ No, the equation is not satisfied.(vii) 5x = 25L.H.S. = 5xBy putting x = 5,L.H.S. = 5 × 5 = 25 = R.H.S.∴ Yes, the equation is satisfied |
