ANSWER

x = 47/4 = 11.75

Step-by-step explanation

First we have to apply the distributive property on the left side of the equation and we can add the terms that contain x:


\begin{gathered} 6x-6\cdot7=(3x-x)+5 \\ 6x-42=(3-1)x+5 \\ 6x-42=2x+5 \end{gathered}

Then we have to put all the x together on the same side of the equation, so we have to subtract 2x from both sides of the equation:


\begin{gathered} 6x-2x-42=2x-2x+5 \\ 4x-42=5 \end{gathered}

Then add 42 on both sides:


\begin{gathered} 4x-42+42=5+42 \\ 4x=47 \end{gathered}

And finally divide both sides by 4:


\begin{gathered} (4x)/(4)=(47)/(4) \\ x=(47)/(4)=11.75 \end{gathered}
