Explanation:

To solve the equation \(4x - 0.2 = 1.9\) for \(x\), we use the addition property of equality. The goal is to isolate the term with \(x\) (which is \(4x\)) first. Currently, we have \(4x - 0.2\) on the left - hand side. To get rid of the \(- 0.2\) and isolate \(4x\), we need to perform the inverse operation of subtraction, which is addition. So we add \(0.2\) to both sides of the equation. This will give us \(4x-0.2 + 0.2=1.9 + 0.2\), or \(4x=2.1\), and then we can proceed to solve for \(x\) by dividing both sides by 4.

Answer:

Add 0.2 to both sides of the equation.
