Best ResponseYou've already chosen the best response.0Solve the system using any method. 5x5y=0 7x8y=8 You can write the first equation as \(8y8x=0\) Add this to the second equation and you will an equation in terms of x only. Find the value of x and then substitute it in any one of the parent equation to get value of y

Best ResponseYou've already chosen the best response.0why would the 1st equation into 8y=8x=0?

Best ResponseYou've already chosen the best response.0\(5x5y=0 \\ \Rightarrow 5(xy)=0 \\ \Rightarrow 8x8y=0 \Rightarrow 8y8x=0\)

Best ResponseYou've already chosen the best response.0Right? Now the second equation has 8y, so we can cancel them out out and life will become happy c:
