Determine whether the equation is an identity?

Question

Determine whether the equation is an identity, a conditional equation, or a contradiction.

8(x + 1) − 4x = 4(x + 2)

This is an identity.

This is a conditional equation.   

This is a contradiction.

Answer 1

8x + 8 - 4x = 4x + 8

4x + 8 = 4x + 8
