Three times the 1st number plus the 2nd number plus twice the 3rd is 5. if three times the 2nd number is subtracted from the sum of the 1st and three times the 3rd number, the result is 2. if the 3rd number is subtracted from two times the 1st number and three times the 2nd, giving a result of 1. find the three numbers
