Which of the following reasons can be used for statement 5 of the proof?
substitution property of equality
How do you know that solutions using substitution gives the answer ot the system of equations?
Here's a mark you use in your math every day, and right now, you have to stopfor a second and understand and accept what it really means:=See that ? That's the "equals" sign. When you write (one quantity) = (another quantity), that means that honestly and truly, those two quantities are not only 'equivalent', butliterally equal in every way. Either one can do anything and everything that the otherone can do, and wherever you see one of them, you can stick the other one in its place,because they're equal in every way.That's why substitution is a legitimate operation. If a statement is true before substitution,it's still true after substitution.
