### Question Description

I’m trying to learn for my Calculus class and I’m stuck. Can you help?

- Write a problem for a classmate to solve that can be translated to a system of two (2) or more equations in at least two (2) variables. Explain your answer.

## Final Answer

Thank you for the opportunity to help you with your question!

Problem:

The sum of two numbers is 60, and their product is 675.

Find the two numbers.

Solution:

Let the two numbers be x and y.

Their sum is 60, therefore

x + y = 60 (1)

Their product is 675, therefore

xy = 675 (2)

From (1), obtain

y = 60 - x (3)

Substitute (3) into (2).

x(60-x) = 675

60x - x^2 = 675

x^2 - 60x + 675 = 0

Factorize to obtain (or you may use the quadratic formula)

(x - 15)(x - 45) = 0

x= 15, or x = 45

When x=15, use (3) to obtain y = 60 - 15 = 45

When x = 45, use (3) to obtain y = 60 - 45 = 15

Answer:

The two numbers are 15 and 45.
