Answer:

Step-by-step explanation:

Step 1:

Age of grace = x

Age of her son = y

Step 2:

   x > 20

x + y ≥ 60

Step 3:

    x +y ≥ 60

        y ≥ -x +60            

Step 4

(45, 22)

x > 20              ;     y  ≥ -x + 60

45 > 20           ;    22  ≥   -45 + 60

                            22  ≥ 15
