thx to all that helped me!!! here is my last question

Answer:
cousin: m-3
uncle: 5m
together: 6m-3
Step-by-step explanation:
if her cousin is 3 years younger, they would be m-3. since their uncle is her age times 5, he would be 5m. add those and you get 5m+m-3. combine the m's (and get 6m), then add the -3 to get 6m-3
Answer:
her younger sister's age: (m - 3)years , her uncles age ( 5m )
sum of their ages : m + m - 3 + 5m = 7m - 3
