Answer 1

Answer:

Hi friends

Step-by-step explanation:

let be the no as x

4x-8=80

x=(80+8)/4

x=22

Answer 2

Given :

• If 8 is subtracted from 4 times a number ,the result is 80.

To find :

• The number

Solution :

Let the number be x.

According to the question,

⟶ 4(Number) - 8 = 80

⟶ 4(x) - 8 = 80

⟶ 4x - 8 = 80

⟶ 4x = 80 + 8

⟶ 4x = 88

⟶ x = 88/4

⟶ x = 22

⟶ The value of x = 22

Therefore, the number is 22.

Let's verify :-

We can verify the value of the number by substituting it in the equation "4(Number) - 8 = 80" if the left hand side will be equal to the right hand side then the value of the number is correct.

⟶ 4(Number) - 8 = 80

Taking LHS,

⟶ 4(Number) - 8

⟶ 4(22) - 8

⟶ 88 - 8

⟶ 80

LHS = 80

RHS = 80

LHS = RHS

Hence, verified!
