Answer:

1=1

Step-by-step explanation:

[tex]12y -(25-(6y -11))=18(y -2)\\\\12y- (36-6y)=18(y-2)\\18y - 36 = 18(y-2)\\18(y-2)=18(y-2)\\1=1 -> identity[/tex]

The other answer is technically correct but if you do RSM, the layout should look like this:

The left - hand side of this equation expands to 18y - 36.

The right - hand side of this equation expands to 18y - 36.

Therefore, this equation is an identity.
