4. At a local pet store there are a total of 7 cats and dogs available for adoption. There is one more than twice as many dogs as cats. If x
represents the number of cats and y represents the number of dogs,
how many cats and dogs are available for adoption at the pet store?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
