[tex]5-4(n+2)=18[/tex]
[tex]
-4(n+2)=18-5
[/tex] [tex]Subtract \ 5 \ from \ both \ sides
[/tex]
[tex]-4(n+2)=13
[/tex]
[tex]n+2= \dfrac{13}{-4} [/tex] [tex]Divide \ both \ sides \ by \ -4[/tex]
[tex]n+2= -\dfrac{13}{4} [/tex]
[tex]n+2= -\dfrac{13}{4}-2 [/tex] [tex]Subtract \ 2 \ from \ both \ sides
[/tex]
[tex]n=- \dfrac{21}{4} [/tex]
