Division property of equality since you have to divide both sides by 7 to find x
Answer:
An equation contains an equal sign so -20 is not an equation, I think it's a typing error
The estimation is -12.25 and it is not right it should be -12&-13
Since there are 5 cats and 2 dogs, divide cats by dogs for the number.
5/2= 2.5
There are 2.5 times more cats than dogs.
I hope this helps!

Y=x^2-4x+8 and 4x+y=12 so y=12-4x, insert y in the quadratic to get
12-4x=x^2-4x+8
12=x^2+8
0=x^2-4=(x-2)(x+2)
So the solutions are x=2 and x=-2.
