Answer 2

To solve the equation $-0.4y - 2.8 = -2.4$, we'll isolate $y$ by performing the necessary operations to move the constants to one side and isolate $y$ on the other side.

Here are the steps to solve the equation:

1. Add $2.8$ to both sides to isolate the variable term on the left side:

   $$-0.4y - 2.8 + 2.8 = -2.4 + 2.8 \\ -0.4y = 0.4$$

2. Divide both sides by $-0.4$ to solve for $y$:

   $$\frac{-0.4y}{-0.4} = \frac{0.4}{-0.4} \\ y = -1$$

So, the solution to the equation $-0.4y - 2.8 = -2.4$ is $y = -1$.
