In September 2022, Mr. Fishman noted that his age was 11 years less than twice his younger sister's age and he
was 2 years younger than his older sister. He also noted that his two sisters are 20 years apart in age. Let x be the age of Mr. Fishman's younger sister. Create at least one equation in order to determine
the younger sister's age in September 2022. Then use the equations you created to solve for all of their ages.
