Answer:
8/56
Step-by-step explanation:
Add up all other marble colors then find the difference from the total.
I earned 5 for x and 12 for y but I'm not sure about the «y»
C+d=14
c-6=d
then you will plug c+6 in the first equation and you will get:
c+c-6=14
then you get
2c=20
c=10, so the cat is ten years old
the cat is 6 years older than the dog, so the dog is 4 years old
hope that helps :)
