ANSWER

No, n=2 is not a solution.

EXPLANATION

The given equation is

[tex]4n - 3 = - 2n + 9n[/tex]

If n=2 is a solution, then it must satisfy this equation.

We substitite n=2 into the equation to get:

[tex]4(2)- 3 = - 2(2)+ 9(2)[/tex]

[tex]8- 3 = - 4+ 18[/tex]

[tex]5 = 14[/tex]

This statement is false

Therefore n=2 us not a solution.
