We can start solving the problem by using algebra. Let's call the first number x and the second number y. From the problem statement, we know that:
y = 4x + 6 (because the second number is 6 more than 4 times the first number)
x + y = 71 (because the sum of the two numbers is 71)
We can substitute the first equation into the second equation:
x + (4x + 6) = 71
5x + 6 = 71
5x = 65
x = 13
Now that we know the value of x, we can substitute it back into the first equation to find the value of y:
y = 4(13) + 6
y = 54
So the two numbers are 13 and 54.
