The sum of three numbers is 105. The third is 11 less than ten times the second. Twice the first is 7 more than three times the second. Find the numbers.
let the second number be x
third = 10x-11
first = (3x+7)/2
x+10x-11 + (3x+7)/2 = 105
2x+20x-22+3x+7 = 210
25x=225x
x= 9 = second
third = 79
first =17
