Question

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

Answer 1

Distributive property.

Answer 2

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
