Answer:
31 + 21 = 52
Step-by-step explanation:
Calculation for the correct sum
First step is to factor 651 which means that 1 * 3 * 7 * 31 will give us 651
Second step is to find 3 possibilities numbers that will give us 10 as the difference
3 possibilities numbers =(31, 21), (93, 7), (217, 3)
Third step is to make use of equation 1 to find the numbers that has 10 as the difference among the 3 possibilities numbers
The number that has 10 as the difference is (31, 21) because 31-21 will gives us 10
Now Equation 1 = X – Y = 10
Where,
X=31
Y=21
Hence,
31 – 21 = 10
Since 31 – 21 gave us 10 as the difference which means that the correct sum will be:
Correct sum =31 + 21 = 52
Therefore the Correct sum is 31 + 21 = 52
