The sum of two numbers is 12 the difference of them is 4 what are the two numbers?x=first number y= second number

Step-by-step explanation:

               x + y = 12   (i)

              x - y = 4 (ii)

add,         2x = 16

                  x = 16/2

                   x = 8

Put x = 8 in (i)

  8 + y = 12

        y = 12 - 8

        y = 4
