Answer: The equation -0.67x + 0.47x = 6.4 is equivalent to -0.2x = 6.4
Step-by-step explanation: To solve this equation for x, we can divide both sides of the equation by -0.2
x = 6.4 / -0.2
x = -32
Therefore, x = -32 is the solution to the equation -0.67x + 0.47x = 6.4
This solution represents the value of x that makes the equation true.
