Question

if 3(n-2)=6 , then what does n-2/n+2

Answer 1

Answer:

$\frac{1}{3}$

Explanations:

Given the expression 3(n-2) = 6

First, we need to get the value of 'n' from this equation:

$\begin{gathered} 3(n-2)=6 \\ 3n-6=6 \\ 3n=6+6 \\ 3n=12 \\ n=\frac{12}{3} \\ n=4 \end{gathered}$

Next is to get the value of the expression n-2/n+2.

Substitute n = 4 into the expression we are looking for as shown:

$\begin{gathered} \frac{n-2}{n+2}=\frac{4-2}{4+2} \\ =\frac{2}{6} \\ =\frac{1}{3} \end{gathered}$

This shows that the value of n-2/n+2 is 1/3
