Answer 2

Answer:

Step-by-step explanation:

Q: A number is 4 times another number, If 21 is added to both the numbers then first number becomes 7/4 times the other number. What are the numbers?​

Let the first no=4x

then another=x

If 21 is added to both the numbers then first number becomes 7/4 times the other number

So 4x+21=7/4(x+21)

4(4x+21)=7(x+21)

16x+84=7x+147

16x-7x=147-84

9x=63

x=63/9=7

Thus the numbers are:

x=7

and 4x=28
