1.	Mona separated thrice the number of notebooks he has from 50 find the result to set up equation and solve them to find the unknown number in the following cases
Answer» (i) x + 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.(viii) 5x = 25L.H.S. = 5xBy putting x = −5,L.H.S. = 5 × (−5) = −25 ≠ R.H.S.∴ No, the equation is not satisfied.(ix) = 2L.H.S. = By putting m = −6,L. H. S. = ≠ R.H.S.∴No, the equation is not satisfied.(x) = 2L.H.S. = By putting m = 0,L.H.S. = ≠ R.H.S.∴No, the equation is not satisfied.(xi) = 2L.H.S. = By putting m = 6,L.H.S. = = R.H.S.∴ Yes, the equation is satisfied.
