Hi Elasia,
suppose 1st number = x
2nd number is 9 less than the 1st = x-9
3rd number is 2 times 1st = 2x
sum of 3 numbers = x+x-9+2x=59
4x-9 = 59
adding 9 on the both sides,
4x= 68
divide by 4 on both sides,
x= 17
1st number = 17
2nd number= x-9 = 17-9= 8
3rd number = 2x= 2*17 =34
Check: 17+8+34=59
