If the sum of all a number's factors (apart from itself) is equal to the original number, then the number is perfect. If this sum is less than the number, it is deficient. If the sum is more than the number, it is abundant. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35 and 70. 1+2+5+7+10+14+35 = 74. Thus the number 70 is abundant.
31 31+39 = 70
the sum of 70 + 30 = 100
The sum is 50+20 = 70
70 - 8 = 62; 62/2 = 31 which is the smaller number; 31 + 8 = 39 which is the other number.
There are many combinations of 2 numbers that sum to 70. Any combination of numbers where the first number is x and the second number is 70-x will sum to 70. For example: 69 and 1 68 and 2 67 and 3 66 and 4...

35 paired is 70
The numbers are: 48+22 = 70
66
31 31+39 = 70
14 x (1 + 4) = 14 x 5 = 70
the sum of 70 + 30 = 100
70 + 19 = 89 or: the sum of 70 and 19 is 89
