Answer:

There are infinite solutions that solve the system
y=0.57-1.59x

Explanation:

  • The solution can be expressed as
    y=0.57-1.59x (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
  • This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
  • Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by
    y=0.57-1.59x, will solve the system. Then we have infinite solutions.
