The equation having – 3 as a solution is:

(a) Given equation is x + 3 = 1

⇒ x = 1 – 3

⇒ x = –2

(b) Given equation is 8 + 2x = 3

⇒ 2x = 3 – 8

⇒ 2x = –5

⇒

⇒ 3x = 1 – 10

⇒ 3x = –9

⇒

⇒ x = –3

(d) Given equation is 2x + 1 = 3

⇒ 2x = 3 – 1

⇒ 2x = 2

⇒

⇒ x = 1

x exceeds 3 by 7, can be represented as
