Gina is 9 years younger than her sister Bridgette Two years ago Bridgette was twice as old as Gina was How old is Gina now

Gina is 11 years old right now:

G = Gina's age now

B = Bridgette's age now

eqn. 1

G + 9 = B

eqn. 2

2(G - 2) = B - 2

substituting from eqn. 1 into eqn 2

2(G-2) = G + 9 - 2

simplifying

2G - 4 = G + 7

subtracting G from both sides and adding 4 to both sides

G = 11 (Gina is 11 years old right now)

so

B = 20

two years ago Gina was 9 and Bridgette was 18 - yup Bridget was twice as old as Gina two years ago and is currently (and has been since Gina was born) 9 years older than Gina.
