suppose 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 \[4x+6y=26\]

the 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)
