Question

Which property is illustrated by the following ?
if 2(x+y)= z, then 2x + 3y= z​

Answer 1

When answering a question like this, ask yourself, “What changed?”

In this case it’s the left side of the equation. In one situation you had 2(x+y) and in the other you had 2x+2y.

What property has you **distribute** the “2 times” outside the parentheses to each individual thing being added inside?
