Question

The sum of two numbers is 16 their difference is8

Answer 1

Answer:

12 and 4

Step-by-step explanation:

12+4=16

12-4=8

Answer 2

Let us assume 1st number as x and second as y

So, x + y = 16 and x - y =8

x-y=8

x=8+y

now replace x with new value in the 1st equation

x+y=16

8+y+y=16

8+2y=16

2y=16–8

2y=8

y=8/2

y=4

now put the value of y in the 1st equation to get value of x

x+y=16

x+4=16

x=16–4

x=12

Hence, the two numbers are 12 and 4
