Question

a positive no. is 5 times another no. if 21 is added to both the no.s, then one of the new no.s becomes twice the other new no. what are the no.s?detailed solution plz​

Answer 1

Answer:

Let first no. be = x

Let second no. be = 5x

Therefore;

5x + 21 = 2(x + 21)

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x = 21

x = 21

5x = 5 * 21 = 105
