You can put this solution on YOUR website! Gina is 9 years younger than her sister Brigget. Two years ago Brigget was twice as old as Gina was. how old is Gina now?
NOW Data:
Brigget age = "x"
Gina age is "x-9"
TWO-YEARS AGO Data:
Brigget age = "x-2"
Gina age = "x-9-2"="x-11"
EQUATION:
Two years ago Brigget was twice as old as Gina.
x-2=2(x-11)
x-2=2x-22
x=20 (Brigget's age NOW.
x-9= 11(Gina's age NOW.
