Question 157678
Let's check your answer.
{{{4n=0}}}
Your answer should look like n=...
Divide both sides by 4 to get,
{{{n=0}}}
If we plug that back in the original equation we get,
3(0-1)=5(0)+3-2(0)
3(-1)=3
-3=3
Your answer leads to a false statement. 
Your answer is not correct.

{{{3(n-1)=5n+3-2n}}}
{{{3n-3=5n+3-2n}}}
{{{3n-3=(5n-2n)+3}}}
{{{3n-3=3n+3}}}
{{{-3=3}}}
This is an example of an inconsistent equation.
There is no "n" that makes this equation work.
There is no solution.
