Best ResponseYou've already chosen the best response.0suppose you have a specific system to solve, like \[2x+3y=13\] and \[x6y=1\] then you can rewrite the first equation \[2x+3y=13\] as an "equivalent" equation \[4x+6y=26\]

Best ResponseYou've already chosen the best response.0the purpose for doing that, is that now you have the same "coefficient' for the \(y\) term, which means when you add the two equations \[4x+6y=26\]\[x6y=1\] you get \[5x=25\]so rewriting either one or both of the equations as and equivalent equation allows you to arrange it so that one variable will add up to zero (cancel)
