Subtraction Property of Equality- For all real numbers a, b, c, if a=b, then a-c=b-c.
Subtraction equal amounts from each side of an equation results in an equivalent
equation.
Addition Property of Equality- For all real numbers a, b, c, then a+c=b+c
Adding equal amounts from each side of an equation results in an equivalent equation.
The Division Property of Equality- For all real numbers a, b, c, if a=b and c, if a =b and
c= 0, then a/c=b/c. Dividing each side of an equation by equal amounts results in an
equivalent equation.
The Multiplication Property of Equality- For all real numbers a, b, c, if a= b, then ac=bc.
Multiplying each side of an equation by equal amounts results in an equivalent equation.
