Answer:

<h2>n = 9</h2>

Step-by-step explanation:

\dfrac{2}{3}(n-6)=5n-43\qquad\text{multiply both sides by 3}\\\\2(n-6)=15n-129\qquad\text{use the distributive property}\\\\2n-12=15n-129\qquad\text{add 12 to both sides}\\\\2n=15n-117\qquad\text{subtract}\ 15n\ \text{from both sides}\\\\-13n=-117\qquad\text{divide both sides by (-13)}\\\\n=9
