8-2(n+3)=n+7-3n
We move all terms to the left:
8-2(n+3)-(n+7-3n)=0
We add all the numbers together, and all the variables
-2(n+3)-(-2n+7)+8=0
We multiply parentheses
-2n-(-2n+7)-6+8=0
We get rid of parentheses
-2n+2n-7-6+8=0
We add all the numbers together, and all the variables
-5!=0
There is no solution for this equation
