Simplifying and Solving Equations
... Since 2 2 = 2 2 is true, the solution, 4, is correct. So, y = 4. Each step in the above example produced a new equation that looks different from the original equation. But even though these equations look different, they all have the same solution (which is 4). Equations that have the same solution ...
