Question

What property does 3/4x - 6 + 6 = -9 + 6 use​

Answer 1

Addition Property of Equality

Explanation:

The addition property of equality says that;

`a=b`

is equivalent to

`a+c=b+c`

The given equation is
`(3)/(4)x-6+6=-9+6`

We can observe that, 6 was added to both sides of

`(3)/(4)x-6=-9` to obtain
`(3)/(4)x-6+6=-9+6`.

Therefore the property use here is the addition property of equality.
