Answer:

[tex]n = -8[/tex]

Step-by-step explanation:

Solve for [tex]n[/tex] :

[tex]20 = 4 + 4n - 6n[/tex]

-Combine like terms:

[tex]20 = 4 + 4n - 6n[/tex]

[tex]20 = 4 - 2n[/tex]

-Switch sides so that variables can be on the left side of the equation:

[tex]20 = 4 - 2n[/tex]

[tex]4 - 2n = 20[/tex]

-Subtract both sides by [tex]4[/tex] :

[tex]4 - 4 - 2n = 20 - 4[/tex]

[tex]-2n = 16[/tex]

-Take [tex]-2n[/tex] and divide them on both sides of the equation:

[tex]\frac{-2n}{-2} = \frac{16}{-2}[/tex]

[tex]n = -8[/tex]

So, the value of [tex]n[/tex] is [tex]-8[/tex].
