5(x-4)=15x

To solve the given equation:

1. Divide both sides of the equation into 5:


\begin{gathered} (5(x-4))/(5)=(15x)/(5) \\ \\ x-4=3x \end{gathered}

2. Subtract x in both sides of the equation:


\begin{gathered} x-x-4=3x-x \\ -4=2x \end{gathered}

3. Divide both sides of the equation into 2:


\begin{gathered} -(4)/(2)=(2x)/(2) \\ \\ \\ -2=x \end{gathered}

Then, the solution for the given equation is x= -2
