You can put this solution on YOUR website! Let x represent one number, and let y represent the other number.
Since the sum of the two numbers is 17, you can write the following
equation:
x + y = 17
Then, since "one number is three less than 4 times the other", you can
write:
x = 4y - 3
Substituting "4y - 3" in place of x in the first equation gives:
4y - 3 + y = 17
5y - 3 = 17
5y = 20
y = 4
Then x = 17 - y = 17 - 4 = 13
Solution: The two numbers are 4 and 13.
