Question

If A = -3n + 2, and B = 5n - 7, what is the value of A + B, in simplest form? I will give you a medal

Answer 1

EXAMPLE:

You are given that:
\(\large\color{green}{ \displaystyle A = 4n - 1 }\)
\(\large\color{blue}{ \displaystyle B = -6n+2 }\)


\(\large\color{black}{ \displaystyle \color{green}{A}+\color{blue}{B} = }\)

\(\large\color{black}{ \displaystyle \color{green}{(4n - 1)}+\color{blue}{( -6n+2)} = }\)

\(\large\color{black}{ \displaystyle 4n - 1-6n+2= }\)

\(\large\color{black}{ \displaystyle 4n -6n+2- 1= }\)

\(\large\color{black}{ \displaystyle -2n+1. }\)
