Answer 1

Answer:

2 and 10

Step-by-step explanation:

Let 2nos. be x and y

x+y=12

x-y=8

x=8 + y

8+2y=12

y=2 and x will be automatically be 10

Answer 2

Answer:

Numbers = x , y

$x + y = 12 \\ x - y = 8 \\ x + y + x - y = 12 + 8$

$2x = 20 \\ x = \frac{20}{2} = 10 \\ 10 + y = 2 \\ y = 12 - 10 \\ = 2$

Hence the numbers are 2 and 10
