let,

the two numbers be x and y

according to the question,

x+y=58............................(1)

x-y=28..............................(2)

subtracting (1) and (2)

   x+y=58

(-)x-y=28

we get 2y=30

              y=15

substitute y in (2)

          we get x-15=28

                    ⇒x=28+15

                    ⇒x=43

therefore, the two numbers are 43 and 15
