Question

Find a number which when multiplied by 5 is increased by 80.​

Answer 1

Step-by-step explanation:

Let the number be x

According to given question,

x×5=x+80

5x=x+80

5x−x=80

4x=80

x=20

Hence, this is the answer.

Answer 2

Let the number be A

5A = A + 80

5A - A = 80

4A = 80

A = 80/4

A = 20

So , the number is 20 .
