Answer 1

Answer:

1. (i) x + 3 = 0
3. LHS = x + 3
5. Put x = 3, we get
7. LHS = 3 + 3 = 6 ≠ RHS
9. So, the equation is not satisfied.
11. (ii) x + 3 = 0
13. LHS = x + 3
15. Put x = 0, we get
17. LHS = 0 + 3 = 3 ≠ RHS
19. So, the equation is not satisfied.
21. (iii) x + 3 = 0
23. LHS = x + 3
25. Put x = -3, we get
27. LHS = -3 + 3 = 0 = RHS
29. So, the equation is satisfied.
31. (iv) x - 7 = 1
33. LHS = x - 7
35. Put x = 7, we get
37. LHS = 7 - 7 = 0 ≠ RHS
39. So, the equation is not satisfied.
41. (v) x - 7 = 1
43. LHS = x - 7
45. Put x = 8, we get
47. LHS = 8 - 7 = 1 = RHS
49. So, the equation is satisfied.
51. (vi) 5x = 25
53. LHS = 5x
55. Put x = 0, we get
57. LHS = 5 * 0 = 0 ≠ RHS
59. So, the equation is not satisfied.
61. (vii) 5x = 25
63. LHS = 5x
65. Put x = 5, we get
67. LHS = 5 * 5 = 25 = RHS
69. So, the equation is satisfied.
71. (viii) 5x = 25
73. LHS = 5x
75. Put x = -5, we get
77. LHS = 5 * (-5) = -25 ≠ RHS
79. So, the equation is not satisfied.
81. (ix) m/3 = 2
83. LHS = m/3
85. Put m = -6, we get
87. LHS = -6/3 = -2 ≠ RHS
89. So, the equation is not satisfied.
91. (x) m/3 = 2
93. LHS = m/3
95. Put m = 0, we get
97. LHS = 0/3 = 0 ≠ RHS
99. So, the equation is not satisfied.
101. (xi) m/3 = 2
103. LHS = m/3
105. Put m = 6, we get
107. LHS = 6/3 = 2 = RHS
