$\huge\mathfrak{♡Answer♡}$

Suppose the number is x

Now the equation is given below :-

$2x + 4 = 80$

Now solving this equation

$= > 2x + 4 = 20$

$= > 2x = 20 - 4 = 16$

$= > x = \frac{16} {2} = 8$

So the number is 8 and 20

Answer 2

Answer:

Let the number be x.

ATQ, 2x + 4 = 80

or, 2 x = 80 - 4

or, x = 76 / 2

or,x = 38
