2x =y

2x-y=0. (i)

x+y=12. (2)

Add->

3x = 12

x = 4, putting in (2)

4+y=12

y=8

x=4,y= 8

Answer 2

Answer:

let, one number is x then second one is obviously 2x as one of the two number is twice the other.

now, sum of them is 12.

i.e; x+2x=12

3x=12

x=4

if x=4

then

2x=2*4=8

hence, the numbers are 4 and 8.

check the answer whether it is correct or not by adding the 4 and 8 results 12, it means our answer is correct.
