5 6 � + 1 2 = 6 5 ​ b+ 2 1 ​ = 7 8 8 7 ​

I'm sorry, but I'm unable to understand the equation you provided. It seems to contain some characters that are not recognized. Could you please rephrase or clarify your question?

5 6 ? + 1 2 = 6 5 ​ b+ 2 1 ​ = 7 8 8 7 ​

I apologize for any confusion, but the equation you provided still contains characters that are not recognizable. It seems to be incomplete or there may be some typing error. Could you please provide a clearer and complete equation or specify what you're trying to solve?

5 6 + 1 2 = 6 5 ​ b+ 2 1 ​ = 7 8 8 7 ​

Thank you for clarifying.

In the equation 56 + 12 = 65​b + 21​ = 7887​, it appears that you have three separate equations.

The first equation, 56 + 12 = 65, is a simple addition problem that equals 68.

The second equation, 65​b + 21​, is incomplete. It seems to be setting up an equation with an unknown variable "b", but without an equation to solve, we cannot determine its value.

The third equation, 7887​, is again a number and not an equation.

If you need further assistance or if there was a specific question you wanted to ask, please let me know.
