Reasoning with Algebra Emily R., Jordan A., Erica W., Serenity W.

Reasoning with algebra means you are working with only __equals__, not congruences.

When reasoning with algebra you use the following properties: (Keep in mind all numbers used can be interchanged with any other __real__ number.   Addition Property: If 2=2, then 2 + 3=2 + 3    Subtraction Property: If 2=2, then 2 – 3=2 - 3    Multiplication Property: If 2=2, then 2(3)= 2(3)    Division Property: If 2=2, then 2/1=2/1    Substitution Property: If 2=2, then 2 can be substituted for 2 in any equation or expression.  Examples: 8x+20=20+3x Given 5x+5=20 Subtraction Property 5x=15 Subtraction Property x=3 Divsion Property
