Let Lehlen be x years old now; then Maria is 2x years now. Five years ago : Maria was 2x-5 years old; Lenlen was x-5 years old. Equation : 2x-5 = 3*(x-5) Simplify and solve 2x-5 = 3x - 15 15-5 = 3x - 2x 10 = x ANSWER. Lehlen is 10 years old now. Maria is 20 years old now. CHECK. 5 years ago M was 15 years old; L was 5 years old. ! Correct !
