​

Answer 1

Answer:

A = 12

Step-by-step explanation:

A = 2B

A - 3 = 3(B - 3)

substitute:

2B - 3 = 3(B - 3)

2B - 3 = 3B - 9

6 = B

A = 2B

A = 12

Answer 2

Answer:

Step-by-step explanation:Let the present age of B be x years.

Therefore the present age of A=2x years.

By the given condition...

A= 3times B's age-3

(-3 is for 3 years ago)

2x=3x-3

2x-3x=-3

-x=-3

X=3 (- and - gets cancelled)

Since x is B's present age.

There present age of B is 3 years.

And the present age of A is 2x

= 2×3

=6 years
