what does n= in 2(5n+3)=8n+2(n+3)

Question

what is the answer to this equation

Answer 1

Let's expand the parentheses:
10n+6=8n+2n+6.
What we can now see is that the left and right sides of the equation are exactly the same: 10n+6, so this is not an equation but an identity.
An identity is just another way to write an expression and cannot be “solved”.
So n, like its name suggests, can be anything.

Answer 2

10n+6=10n+6.                 10n-10n=0.            6-6=0.                0=0.          N=1.
