Question

What is an equal equation to (2b+1)-b

Answer 1

To have an equation, you need to have two expression, and an equal sign (=) between them.

This is not an equation, but rather an expression. In order to simplify it, you simply have to subtract
`b` from the quantity in the parenthesis:

`(2b+1)-b = 2b+1-b = 2b-b+1 = b+1`
