check whether n=1 satisfies the equation n+5=19 or n
Answers
Answer: i) x + 3 = 0
By putting x = 3
L.H.S. = 3 + 3 = 6 ≠ R.H.S.
Hence, the equation is not satisfied.
(ii) x + 3 = 0
By putting x = 0
L.H.S. = 0 + 3 = 3 ≠ R.H.S.
Hence, the equation is not statisfied.
(iii) x + 3 = 0
By putting x = – 3
L.H.S. = – 3 + 3 = 0 = R.H.S.
Hence, the equation is satisfied.
(iv) x – 7 = 1
By putting x = 7
L.H.S. = 7 – 7 = 0 ≠ R.H.S.
Hence, the equation is not satisfied.
(v) x – 7 = 1
By putting x = 8
L.H.S. = 8 – 7 = 1 = R.H.S.
Hence, the equation is satisfied.
(vi) 5x = 25
By putting x = 0
L.H.S. = 5 × 0 = 0 ≠ R.H.S.
Hence, the equation is not satisfied. (vii) 5x = 25
By putting x = 5
L.H.S. = 5 × 5 = 25 = R.H.S.
Hence, the equation is satisfied.
(viii) 5x = 25
By putting x = – 5
L.H.S. = 5 × (–5) = –25 ≠ R.H.S.
Hence, the equation is not satisfied. (ix) m/3=2
By putting m = – 6
L.H.S.R.H.S.=−=−≠632
Hence, the equation is not satisfied.
(x) m/3=2
By putting m = 0
L.H.S. = 03 = 0 ≠ R.H.S.
Hence, the equation is not satisfied.
(xi) m/3= 2
By putting m = 6
L.H.S. = 63 = 2 = R.H.S
Hence, the equation is satisfied.
