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.

Find the weight of Tweedledum and Tweedledee

In this hypothetical problem written by Richard Rusczyk:

Tweedledum says, "The sum of your weight and twice mine is 361 pounds." Tweedledee says, "Contrariwise, the sum of your weight and twice mine is 362 pounds." If they are both correct, how much do Tweedledum and Tweedledee weigh together?

Tweedledum and Tweedledee weigh 120 and 121 pounds respectively.

(NB: Tweedledum and Tweedledee never actually had this converstion, and in the original book their weight remains a mystery...)
