Calculation mistakes should be avoided while solving this problem, if a small mistake is done then the final answer will get interrupted. So, calculation mistake should be avoided and each and every step should be done in a careful manner to get a correct final answer.
Complete step-by-step solution:
From the question, we were given to solve \[5n-6=39\]. So, it is clear that we have to find the value of n in the given equation \[5n-6=39\].
Let us assume the given equation as equation (1).
\[5n-6=39.....(1)\].
Now let us add 6 on both sides of equation (1), then we get
\[ \Rightarrow 5n-6+6=39+6 \]
\[ \Rightarrow 5n=45 \]
Let us assume the given equation as equation (2), then we get
\[5n=45......(2)\]
Now, let us divide the equation (2) on both sides by 5, then we get
\[\Rightarrow \dfrac{5n}{5}=\dfrac{45}{9}\]
Let us assume this as equation (3).
\[\dfrac{5n}{5}=\dfrac{45}{9}.....(3)\]
Now let us solve the equation (3) to find the exact value of n as shown below:
\[\Rightarrow n=5\]
Let us assume this as equation (4),
\[n=5.....(4)\]
From equation (4), it is clear that the value of n is equal to 5.
So, by solving \[5n-6=39\], we get that the value of n is equal to 5.
