1. ## Algebraic equation

4 (x + 3) + 5 (x - 4) - just for the sake of the add/subtract sign. I can't remember

2. Are you looking to expand this equation like so?

$4 (x + 3) + 5 (x - 4)$

$4 x + 12 + 5 x - 20$

$9 x -8$

Thanks. I just wanted to clarify the sign in the 2nd bracket. I was right.

You called that an equation; it is not an equation, just an expression.

Ok, sorry you're right, but now I know what I wanted to know
