Numbers 3 & 4 are D, let me know if you want me to explain
Let L and S be the number of large and small dogs respectively.
L+S=8 so we can say L=8-S
5S+8L=55, using L found above in this equation yields:
5S+8(8-S)=55
5S+64-8S=55
-3S+64=55
-3S=-9
S=3, since L=8-S
L=5
So Ryan walked 3 small dogs and 5 large dogs.
For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

Now that we have the value of x, plug it into either equation to solve for y:

<h3><u>In short, the solution to this equation is (3,-5).</u></h3>
