21 + 43=74 and 43-21=12, so your answer is 21+43
21 and 22
Two numbers with a sum of 47 are 1 and 46, 2 and 45, 3 and 44, 4 and 43, etc.
41 and 7 43 and 5
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
The two numbers are 43 and 68. 43 + 68 = 111, while 68 - 43 = 25
21 + 43=74 and 43-21=12, so your answer is 21+43
43 and 2
44
17 and 26
This is easily solved by using two equations in 2 unknowns and solving the system. x + y = 111 x - y = 43 If have not yet had the pleasure of studying algebra and the answer is important to you, you could hope the numbers are positive integers and try all pair of numbers whose sum is 43: 1,42 2,41 3,40 and so on, until you find a pair whose difference is 43.
The numbers are 43 and 45.
21 and 22
Two numbers with a sum of 47 are 1 and 46, 2 and 45, 3 and 44, 4 and 43, etc.
There's some information missing here, but it's likely the numbers you're looking for are 11 and 6. They have a sum of 17, a difference of 5, and 17 x 5 = 85. Depending on what you left out, 43 and 42 might also work.
The numbers are 43 and 45.
