Question

the difference between ages of a and b is 16 years 6 years before a age is 3 times of b age find their ages​

Answer 1

Step-by-step explanation:

Answer 2

Answer:

Age of a=30 years and b =14 years

Step-by-step explanation:

Let age of a be x years

     age of b be y years

       by first condition,

    x-y=16   .....................1

      by second condition,

     x-6=3(y-6)

     x-6=3y-18

      x-3y= -18+6

      x-3y= -12   ............2

     subtracting both equations,

            x-y=16

            x-3y= -12

          -   +      +

                2y=28

                 y=28/2

                ∴ y=14

                 

             placing y=14 in eqation 1

                   x-y=16

                   x-14=16

                   x=16+14

                   x=30

         

                  ∴ a=30 years and y=14 years
