The difference between 3/2 of Adriana's age and her age decreased by 6 is less than her age. In addition, the difference between three times her age and her age increased by 14 is less than her age. At what stage of her development is Adriana?
Let x---------> Adriana s age
we know that (3/2)x-(x-6) < x------> (3/2)x-x+6 < x----->(1/2)x-x < -6----> (1/2)x > 6 x> 12
and 3x-(x+14) < x-----> 3x-x-14 < x------> 2x-x < 14----> x < 14
the solution for the age of Adriana is the interval (12,14)
