Solution Steps

To solve the equation \(-1.6r + 5 = 1.8\), we need to isolate the variable \(r\). First, subtract 5 from both sides of the equation to eliminate the constant term on the left side. Then, divide both sides by \(-1.6\) to solve for \(r\).

Step 1: Rearranging the Equation

Starting with the equation: \[ -1.6r + 5 = 1.8 \] we subtract 5 from both sides: \[ -1.6r = 1.8 - 5 \] This simplifies to: \[ -1.6r = -3.2 \]

Step 2: Solving for \( r \)

Next, we divide both sides by \(-1.6\): \[ r = \frac{-3.2}{-1.6} \] This simplifies to: \[ r = 2.0 \]

Final Answer

The solution for \( r \) is: \[ \boxed{r = 2.0} \]
