Step-by-step explanation:
Given expression is [tex]8b -2b -4[/tex]
To simplify any expression we combine like terms
Any expression contains constant and variables.
the terms that contains variables are 8b and -2b .the constant term is -4
To simplify combine the like terms 8b and -2b
[tex]8b-2b= 6b[/tex]
[tex]8b -2b -4[/tex]
[tex]6b -4[/tex]
So the simplified expression is [tex]6b -4[/tex]
