sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:

Answer 1

a) Let Kim's age be k, then Kim's sister's age is k/2

k+
`(k)/(2)`=24

b) k+
`(k)/(2)`=24

1
`(1)/(2)`k=24

k=16

`(k)/(2)`=8

Kim's age is 16 while her sister's age is 8.
