Answer 2

To solve the equation, let's first simplify both sides of the equation step by step:

Given equation: -3(2x - 4) - 4.2 = 1.2(-5x + 0.5)

Step 1: Distribute the terms inside the parentheses: -3 * 2x + (-3) * (-4) - 4.2 = 1.2 * (-5x) + 1.2 * 0.5

Step 2: Simplify the expressions: -6x + 12 - 4.2 = -6x + 0.6

Step 3: Combine like terms: -6x + 7.8 = -6x + 0.6

Step 4: Get all the x terms on one side by adding 6x to both sides: -6x + 6x + 7.8 = -6x + 6x + 0.6

Step 5: Simplify: 7.8 = 0.6

The equation simplifies to 7.8 = 0.6, but this is not possible since there is no value of x that satisfies this equation. Therefore, there is no solution to the original equation.
