Questions: -1.6 r+5=1.8

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 $r$.

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

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