(6.2n-8.3)+(-9.1+1.4n)

To simplify this expression:

1. Remove the parenthesis: To remove parenthesis you need to know that the symbol outside parenthesis affects all the terms inside parenthesis.


\begin{gathered} +(-)=- \\ -(+)=- \\ -(-)=+ \\ +(+)=+ \end{gathered}

The given expression after remove the parenthesis is:


6.2n-8.3-9.1+1.4n

2. Add or substract similar terms: similar terms have the same variable in this case n, or don't have any variable:


7.6n-17.4Then, the given expression simplified is 7.6n - 17.4
