# The equation having 5 as a solution is:

A. 4x + 1 = 2

B. 3 – x = 8

C. x – 5 = 3

D. 3 + x = 8

Answer :

(a) Given equation is 4x + 1 = 2

⇒ 4x = 2 – 1

⇒

⇒

(b) Given equation is 3 – x = 8

⇒ –x = 8 – 3

⇒ –x = 5

⇒ x = –5

(c) Given equation is x – 5 = 3

⇒ x = 3 + 5

⇒ x = 8

(d) Given equation is 3 + x = 8

⇒ x = 8 – 3

⇒ x = 5
