let one number be = x

let another number be = y

so according to the question

x = 5y (i)

so according to the other equation

x + 21 = 2( y + 21)

now putting the value of "x" from equation (i)

5y + 21 = 2y + 42

3y = 21

\frac{21}{3} = 7

so the number y = 7

and other number be =7 \times 5 = 35

so the numbers are 7 and 35
