$n=17$

We will remove the parenthesis by multiplying each term within the parenthesis with the term outside the parenthesis. Then, we will put the variables and constants on opposite sides of the equality sign to simplify: Step 1: $-2(n-1)+4(2n-3)=4(n+6)$ Step 2: $-2n+2+8n-12=4n+24$ Step 3: $-2n+8n-4n=24+12-2$ Step 4: $2n=34$ Step 5: $n=17$
