Answer:

Step-by-step explanation:

To prove that -10 is the solution to the given equation, we need to substitute -10 for both x and c and verify if the equation holds true.

Let's start by substituting -10 for x and c in the equation:

1/4(8(-10) - 20) = 6(-10) - (-10 - 25(-10))

Simplifying the equation:

1/4(-80 - 20) = -60 - (-10 + 250)

1/4(-100) = -60 - (-10 + 250)

-25 = -60 - (240)

-25 = -300

The equation is not true when we substitute -10 for x and c. Therefore, -10 is not a solution to the given equation.
