Question

4n − 3 = −2 n + 9n = 2 Is 2 the solution? yes or no, how do you know?

Answer 1

`</p><p>4n-3=-2n+9n \\</p><p>6n-3=9n \\</p><p>3n=-3 \\</p><p>n=\boxed{-1}</p><p>`

2 is not a solution but -1.

Answer 2

No, n=2 is not a solution.

Step-by-step explanation

The given equation is

`4n - 3 = - 2n + 9n`

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

We substitite n=2 into the equation to get:

`4(2)- 3 = - 2(2)+ 9(2)`

`8- 3 = - 4+ 18`

`5 = 14`

This statement is false

Therefore n=2 us not a solution.
