Y = 4x - 11
x = 2y - 13

    x = 2(4x - 11)- 13
    x = 2(4x) - 2(11) - 13
    x = 8x - 22 - 13
    x = 8x - 35
<u>- 8x - 8x </u>
<u> -7x</u> = <u>-35</u>
-7    -7
   x = 5
y = 4x - 11
y = 4(5) - 11
y = 20 - 11
y = 9
(x, y) = (5, 9)

Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate $2(4)+4(4)+1(4)+5(4)+1(2)+3(2)$ , right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want $2(4)+4(4)+1(4)+5(4)+1(2)$ .

We multiply it out to get $8+16+4+20+2$ .

We add these up to get $50$ .

So, our answer is $\boxed{50}$ legs.
