Answer:
a. 2
b. 11
Step-by-step explanation:
a.
(i) let's assume x = 5, then
putting value of x in the equation, we get
5 + 9 = 11
=> 14 ≠ 11, since LHS ≠ RHS
Therefore, x ≠ 5
(ii) Let's assume x = 2, then
putting value of x in the equation, we get
2 + 9 = 11
=> 11 = 11, since LHS = RHS
Therefore, x = 2.
b.
(i) let's assume b = 12 , then putting value of b in the equation, we get
12 - 6 = 5
=> 6 ≠ 5, since LHS ≠ RHS
Therefore, b ≠ 12.
(ii) let's assume b = 13 , then putting value of b in the equation, we get
13 - 6 = 5
=> 7 ≠ 5, since LHS ≠ RHS
Therefore, b ≠ 13.
(iii) let's assume b = 11 , then putting value of b in the equation, we get
11 - 6 = 5
=> 5 = 5, since LHS = RHS
Therefore, b = 11.
