$n=2$
We start with the given equation: $n+5(n-1)=7$ We use the distributive property to expand the left side of the equation: $n+5n-5=7$ We add 5 to both sides of the equation: $n+5n-5+5=7+5$ We combine like terms on both sides of the equation: $6n=12$ Finally, we divide by $6$ on both sides of the equation: $n=\frac{12}{6}=2$
