Solve the equation. \[ 0.2 x-0.3=0.1 x+4 \]

Step 1 ：Let's start by solving the equation \(0.2x - 0.3 = 0.1x + 4\).

Step 2 ：First, we subtract \(0.1x\) from both sides of the equation to get \(0.1x - 0.3 = 4\).

Step 3 ：Next, we add \(0.3\) to both sides of the equation to isolate \(x\) on one side. This gives us \(0.1x = 4.3\).

Step 4 ：Finally, we divide both sides of the equation by \(0.1\) to solve for \(x\). This gives us the final answer: \(\boxed{43}\).
