Question

when 5 is added to a certain number and the result is multiplied by 3, the final answer is 27. What is the original number

Answer 1

Answer:

Let the number be x

5 is subtracted from a certain number means it will be x - 5

The result is multiplied by 7, the final result is 63,

7 (x - 5) = 63

7x - 35 = 63

7x = 63 + 35

7x = 98

x = 98/7

x = 14

The number is 14

Answer the number is 14 and the equation is 7 (x - 5) = 63

Step-by-step explanation:

Answer 2

Using the appropriate arithmetic operation, the value of the original number is 4

Let the number be : p

5 added to p :

• 5 + p

Multiply the addition by 7 :

• (5 + p) × 3 = 27

We can solve for p thus :

15 + 3p = 27

3p = 27 - 15

3p = 12

p = 12/3

p = 4

Therefore, the original number is 4.
