Answer:
Jim's sister age now is ( 2x - 2) years.
Step-by-step explanation:
Given
Jim will be x years old in two years
At that time, his sister will be twice as old as he will be
Thus, the age of sister in two years = 2*Jim's age in 2 years
the age of sister in two years = 2*x years = 2x years
Jim's sister age now will be 2 years lesser than the age found above which is her age after two year
Jim's sister age now = age of sister in two years - 2 years
Jim's sister age now = 2x years - 2 years
Jim's sister age now = ( 2x - 2) years
