Question

what 2 numbers have a sum of 12 and a difference of 8

Answer 1

Answer:

The sum of 12 and 8 is 12 add 8 which is 20. The difference between 12 and 8 is 12 minus 8 which is 4.

Answer 2

Answer:

The two numbers are 10 and 2.

Step-by-step explanation:

Let the two numbers be a and b respectively.

Where, a > b

Their sum = 12

Then, a + b = 12 ---------> eq no. 1

Their difference = 8

Then, a - b = 8 ---------> eq no. 2

Add eq no. 1 and 2

a + b = 12

a - b =  8

_________

2a + 0 = 20

2a = 20

a = 20 / 2

a = 10

substitute a = 10 in eq no. 1

a + b = 12

10 + b = 12

b = 2

Therefore, the two numbers are 10 and 2.
