To determine the best method to solve the given system of equations, let's analyze the equations:
1. \( 0.5x - 1.4y = 5.8 \)
2. \( y = -0.3x - \frac{1}{5} \)
The second equation is already solved for \( y \), which makes it convenient for substitution. We can substitute the expression for \( y \) from the second equation into the first equation. Therefore, the best method to solve this system is:
