The sum of three numbers is 113. The second number is 4 times than the third. The third number is 5 less than the first. What are the numbers?

Answer 1

n = the first number

n - 5 = the third number

4(n - 5) = the second number

The sum of the three numbers is 113, so

n + (n - 5) + 4(n - 5) = 113

Solve for n and finish from here.
