Best ResponseYou've already chosen the best response.0lol. since 4=4 i don't think there is infinite solutions

Best ResponseYou've already chosen the best response.0Here's how you prove that you have an infinite number of solutions: Can you make get equation 2 by multiplying equation 1 by something? Let's consider it: $$4x + y = 4$$ This is the same thing as: $$y = 4  4x$$ Since all we need to do is pass the x to the other side. So the two equations are really the same equation. So any points that is a solution for the first equation will work for the second equation. But if you look at the first equation, you see that it's the equation for a line. Therefore, any point on that line will be a solution to the second equation as well. This means that you have an infinite number of solutions.

Best ResponseYou've already chosen the best response.0i don't agree since it clearly states that "solve by substitution"

Best ResponseYou've already chosen the best response.0B) is correct, even if you use substitution. The substitution gives 4=4 which means that the statement is always true for any (x,y) as long as (x,y) is on the line 4x+y=4.

Best ResponseYou've already chosen the best response.0right nomo  the 2 equations are the same and u can fit infinite values of x and corresponding values of y into the equation
