Complete the last column of the table
S. No. | Equation | Value | Say, whether the Equation No. is Satisfied. (Yes/ No) |
---|---|---|---|
(i) | x + 3 = 0 | x = 3 | |
(ii) | x + 3 = 0 | x = 0 | |
(iii) | x + 3 = 0 | x = – 3 | |
(iv) | x – 7 = 1 | x = 7 | |
(v) | x – 7 = 1 | x = 8 | |
(vi) | 5x = 25 | x = 0 | |
(vii) | 5x = 25 | x = 5 | |
(viii) | 5x = 25 | x = – 5 | |
(ix) | 3m=2 | m = – 6 | |
(x) | 3m=2 | m = 0 | |
(xi) | 3m=2 | m = 6 |
(i) x + 3 = 0
L.H.S. = x + 3
By putting x = 3,
L.H.S. = 3 + 3 = 6 ≠ R.H.S.
∴ No, the equation is not satisfied.
(ii) x + 3 = 0
L.H.S. = x + 3
By putting x = 0,
L.H.S. = 0 + 3 = 3 ≠ R.H.S.
∴ No, the equation is not satisfied.
(iii) x + 3 = 0
L.H.S. = x + 3
By putting x = - 3,
L.H.S. = - 3 + 3 = 0 = R.H.S.
∴ Yes, the equation is satisfied.
(iv) x - 7 = 1
L.H.S. = x - 7
By putting x = 7,
L.H.S. = 7 - 7 = 0 ≠
∴ R.H.S. No, the equation is not satisfied.
(v) x - 7 = 1
L.H.S. = x - 7
By putting x = 8,
L.H.S. = 8 - 7 = 1 = R.H.S.
∴ Yes, the equation is satisfied.
(vi) 5x = 25
L.H.S. = 5x
By putting x = 0,
L.H.S. = 5 × 0 = 0 ≠ R.H.S.
∴ No, the equation is not satisfied
(vii) 5x = 25
L.H.S. = 5x
By putting x = 5,
L.H.S. = 5 × 5 = 25 = R.H.S.
∴ Yes, the equation is satisfied.
(viii) 5x = 25
L.H.S. = 5x
By putting x = - 5,
L.H.S. = 5 × ( - 5) = - 25 ≠ R.H.S.
∴ No, the equation is not satisfied.
(ix) 3m= 2
L.H.S. = 3m
By putting m = - 6,
L.H.S. = 3−6= - 2 ≠ R.H.S.
∴ No, the equation is not satisfied. ≠ R.H.S.
(x) 3m = 2
L.H.S. = 3m
By putting m = 0,
L.H.S. =30 = 0
L.H.S. = R.H.S.
∴ Yes, the equation is satisfied
(xi) 3m = 2
L.H.S. =3m
By putting m = 6,
L.H.S. = 36 = 2
L.H.S. = R.H.S.
∴ Yes, the equation is satisfied
