5-4(n+2)=18 


-4(n+2)=18-5
 

  Subtract \ 5 \ from  \ both \ sides
 

-4(n+2)=13

 

n+2= \dfrac{13}{-4}    Divide \ both \ sides \ by \ -4

<span>n+2= -\dfrac{13}{4}  
</span>
<span>n+2= -\dfrac{13}{4}-2    </span>Subtract \ 2 \ from \ both \ sides&#10;<span>
</span>
n=- \dfrac{21}{4}

Decimal \ Form: -5.25

According to y = mx + b, whereas b is the y-intercept

so if b is positive, b has to be larger than 0
