If, in 7 years, susan will be 2 times as old as she was 3 years ago, what is susan’s present age?

13

Step-by-step explanation:

Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)

Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:

x+7 = 2(x-3)

x+7 = 2x-6

x = 13
