Answer 3

To solve the equation $1.6(7-5x) + 4(2-0.4x) = 0$, you can follow these steps:

1. Distribute the terms on both sides of the equation.
2. Combine like terms.
3. Solve for $x$.

Let's go through the steps:

$$\begin{align*} 1.6(7-5x) + 4(2-0.4x) &= 0 \\ 11.2 - 8x + 8 - 1.6x &= 0 \quad \text{(Distribute)} \\ 19.2 - 9.6x &= 0 \quad \text{(Combine like terms)} \\ -9.6x &= -19.2 \quad \text{(Subtract 19.2 from both sides)} \\ x &= \frac{-19.2}{-9.6} \quad \text{(Divide by -9.6)} \\ x &= 2 \end{align*}$$

Therefore, the solution to the equation is $x = 2$.
