\(4(x+1)-ax=x+5\)
\(4x+4-ax=x+5\) \(Expand\)
\(4x-ax=x+5-4\) \(Subtract \ 4 \ from \ both \ sides\)
\(4x-ax=x+1\)
\(4x=x+1+ax\) \(Add \ ax \ to \ both \ sides\)
\(4x-x=1+ax\) \(Subtract \ x \ from \ both \ sides\)
\(3x=1+ax\)
\(3x-ax=1\) \(Subtract \ ax \ from \ both \ sides\)
\(x(3-a)=1\)
\(x= \dfrac{1}{3-a}\)
