Which equation is an identity?

3 (x - 1) = x + 2 (x + 1) + 1

x - 4 (x + 1) = - 3 (x + 1) + 1

2x + 3 = 2 x plus 3 equals StartFraction one-half EndFraction left-parenthesis 4 x plus 2 right-parenthesis plus 2. (4x + 2) + 2

StartFraction one-third EndFraction left-parenthesis 6 x minus 3 right-parenthesis equals 3 left-parenthesis x plus 1 right-parenthesis minus x minus 2. (6x - 3) = 3 (x + 1) - x - 2
