Answer 2

Let the whole number = x

We have to find, the value of whole number.

Solution:

According to question,

28 is added to twice of a whole number = 78

∴ 2x + 28 = 78

Subtracting both sides by 28, we get

2x + 28 - 28 = 78 - 28

⇒  2x = 50

Dividing both sides by 2, we get

$\dfrac{ 2x }{2}$ = $\dfrac{50}{2}$

⇒ x = 25

∴ The whole number (x) = 25

Thus, the value of a whole number is "equal to 25".
