Answer:

A = 15  B = 25       in four years  19+29 = 48

Step-by-step explanation:

age A and B ratio is 3 to 5

A+4 + B+4 = 48

    A + B  = 40

    A/B = 3/5     A = 3B/5

    A + B  = 40

 3B/5 + B  = 40

   3B  + 5B = 200          multiple both sides by 5

       8B  = 200

         B  =  25

         A  = 3B/5

         A  = 3(25)/5

         A  = 15
