Translate this word problem as a system of equations and then solve using substitution. The sum of two numbers is 84. One number is three times the other. Find the numbers.

Put your answer in this form:
The numbers are 3 and 6.

The numbers are 21 and 63

Step-by-step explanation:

let one number be x

let the other number be 3 times the other = 3x

3x + x = 84

4x = 84

x = 21

3x = 3×21 = 63

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.
