Answer 2

To solve the equation, we need to simplify and solve for the variable x. Let's go through the steps:

1. Distribute the terms: 0.2(x + 5) + 0.5(2 - x) = -0.3(x + 5)

0.2x + 0.2(5) + 0.5(2) - 0.5x = -0.3x - 0.3(5)

2. Simplify: 0.2x + 1 + 1 - 0.5x = -0.3x - 1.5

3. Combine like terms: (0.2x - 0.5x) + 2 = -0.3x - 1.5

-0.3x + 2 = -0.3x - 1.5

4. Now, we can move all terms involving x to one side: -0.3x + 0.3x + 2 = -0.3x - 0.3x - 1.5

2 = -1.5

Since the equation has resulted in a contradiction (2 ≠ -1.5), there is no solution for this equation. It means there is no value of x that satisfies this equation.
