Is this an example of multiplicative equality

  1. Sep 28, 2011 #1
    good day,

    this is the multiplication property of equality rule

    a * b = b * c

    but is this the multiplicative equality too: a * x = b

    thank you so much

    have a good day

    not exactly, equality allows same operations across the equal, so to demonstrate you have to show one equation equal and then change it, such as:

    if a = b then a*c = b*c is multiplicative equality

    showing that when you multiply something on one side you do it equally on the other...
