Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.

To get standard form we need to move variables with their coefficients on one side and numbers on other side. Standard form looks like this:
Ax + By = C
y - 4 = 3x/4 +6
y - 3x/4 = 6+4
y - 3x/4 = 10
