Answer:
[tex]7x+2[/tex]
Step-by-step explanation:
Alright. First, we have to remember that anything, even a minus sign, directly outside of a term in parentheses means that the term is being multiplied by that number or sign outside of it. A minus sign simply means -1.
I'm going to show you one method. There might be another one, but this method will be useful later in algebra.
So, we've established that a minus sign is actually -1. Now, let's rewrite the equation.
[tex](8x+6)-1(x+4)[/tex]
We'll simplify this now by removing the parentheses and distributing that -1.
[tex]8x+6-x-4[/tex]
Rearrange.
[tex]8x-x+6-4[/tex]
Combine like terms.
[tex]7x+2[/tex]
So, [tex](8x+6)-(x+4)[/tex] equals [tex]7x+2[/tex].
