Question

“The sum of half a number and 12 is 6”

Answer 1

Solution :

Let, the number be A

Given, A/2 + 12 = 6

⇒ (A + 24)/2 = 6

⇒ A + 24 = 12

⇒ A = 12 - 24

⇒ A = - 12

∴ the required number is (- 12). (Ans.)

Answer 2

Answer:

x=-12

Step-by-step explanation:

suppose,

The number = x

half a number=1/2 x=x/2

The sum of half a number and 12 is 6

x/2 + 12=6

x/2=6-12

x/2=-6

x=-12
