The sum of Lisa's age and Myra's age is 19. In 10 years, Lisa will be 5 years older than Myra. How old is each girl now?

we know that the distance between two people's ages will never be different, so Lisa will always be 5 years older than Myra. We can think of Myra's age as x, and because Lisa is 5 years older, she can be x+5. To find x, we can set up an equation where the sum of their ages is 19 --> x + (x+5) = 19. Combine like terms, and you have 2x+5=19. By solving for x, you should get x(Myra)=7, and x+5(Lisa)=12. To find their ages in 10 years, simply add 10 to each number.
