The required equation is:

$a = 2b-3$

Step-by-step explanation:

Given

Let a be Anne's Age

and

b be Betty's age

Now we will onvert the given word problem in the form of equation step by step

"twice Betty's age." will be represented by $2b$

Then

"3 years younger than twice Betty's age." will be represented as: $2b-3$

Now

"Betty's sister, Anne, is 3 years younger than twice Betty's age."

$a = 2b-3$

Hence,

The required equation is:

$a = 2b-3$
