The sum of 3 number is 43. First number is 5 more than second number. The 3rd number is 8 less than twice the first number . What are the three number
=========================
Let n = the 1st number
Then the 2nd number = n - 5
And the 3rd number = 2n - 8
Their sum = 43:
n + (n-5) + (2n-8) = 43
4n - 13 = 43
4n = 56
n = 14
So the numbers are 14, 9 and 20
