Let's solve the equation:


0.4(x-7)=18

First, let's divide both sides by 0.4 :


0.4(x-7)=18\rightarrow(0.4(x-7))/(0.4)=(18)/(0.4)\rightarrow x-7=45

Now, we'll add 7 to both sides:


\begin{gathered} x-7=45\rightarrow x-7+7=45+7 \\ \\ \Rightarrow x=52 \end{gathered}

This way, we can conclude that x is 52
