Question

Which property was used to write the equation in step 2?

Answer 1

For this case we have that by definition, the distributive property establishes that:

$a (b + c) = ab + ac$

So, if we have:

$5 (x-7) = 55$

When applying distributive property to the terms within the parenthesis we have:

$5x-35 = 55$

The distributive property was used to write the second step.

Answer:

Distributive property
