I'm thinking of two numbers. The first number is three times the second. The second number is five less than two times the first. What are my numbers?

1 answer

Easy to translate from English to Math.
Let the 2nd number be x and the first one y

"The first number is three times the second"
y = 3x

"The second number is five less than two times the first"

x = 2(3x) - 5
-5x = 5
x = 1
then y = 3

The first number is 3 and the second is 1

check:
Is the first number three times the second? YES
second number: 1
two times the first: 6
is 1 less than 6 by 5 ? YES
