Answer 2

$\huge\fbox\pink{Solution}$

(i) 5p + 2 = 17

For p = 1, LHS

= 5 × 1 + 2 = 5 + 2 = 7 ≠ 17 (RHS)

For p = 2, LHS = 5 × 2 + 2

= 10 + 2 = 12 ≠ 17 (RHS)

For p = 3, LHS = 5 × 3 + 2

= 15 + 2 = 17 = 17 (RHS)

Since the given equation is satisfied for p = 3 Thus, p = 3 is the required solution.
