The sum of two numbers is 23. The first number is 3/20 of the second number. What are the numbers?
Thepotemich [5.8K]

Answer:

Here's what i know:

x + y = 23

3y / 20 =x

 

Here we can use substitution to help find our answer:

y + 3y/20 = 23

20y/20 + 3y/20 = 23

23y/20 = 23

23y = 23 * 20

y = 23 * 20 / 23

y = 20

 

x + 20 = 23

x = 3
