Step-by-step explanation:

a) x + 5 = 3 (x = 2)

⇒ (2) + 5

⇒7

& 7 ≠ 3

Hence, it is not a solution

--------------------------------------

b) 8 n + 5 = 21 (n = 2)

⇒8(2)+5

⇒16+5

⇒ 21

& 21=21

Hence, it is a solution

--------------------------------------

c) 4 s + 3 = 5 ( s = -2)

⇒4(-2)+3

⇒ -8+3

⇒ -5

& -5 ≠ 5

Hence, it is not a solution
