Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds. Which system of equations could be used to find the weight of each animal?

C

Step-by-step explanation:

First let’s identify that:

y = the kitten

x = the cat

Part 1 : The kitten weighs 3 pounds less than half the weight of Callie's cat.

We know that the kitten is half the size of the cat, which means the equation now looks like this:

x = y

But we also know that the kitten is 3 less than that equation, so now the equation is:

x = y -3

Part 2: Together the cat and the kitten weigh 18 pounds

Now, we have to use the other statement:

y + x = 18

But, that’s not one of the options, so we have to switch the x around and make it negative.

y = -x + 18

These are your answers!
