Explanation:

The given is,

The sum of two numbers is 21

The second number is six times the first number

Step:1

Let, m - First number

n - Second number

Step:2

From given,

n - 6m ( The second number is six times the first number )

Equation becomes,

Sum = m + n

Where,

21 = m + ( 6m )

21 = 7m

m = 3

Substitute m value n becomes,

n = 6m

= (6 × 3)

n = 18

Result:

The two numbers are 3 and 18, if the sum of two number is 21 and the second number is six times the first number.
