Question

Is the equation -2(4-x) = 2x+8 an identity?

Answer 1

Answer: not an idenfity

Explanation:

`-2(4-x)=2x+8\\(-2)(4)+(-2)(-x)=2x+8\\-8+2x=2x+8\\2x-8\\eq 2x+8`

Answer 2

No

Explanation:

-2(4-x) = 2x+8

Distribute the -2 on the left hand side

-2 *4 -2*-x = 2x+8

-8 +2x = 2x+8

They are not equal so it is not an identity
