In the equation 5x - 5 = 20, what is the value of x?

• A. 5
• B. 6
• C. 4
• D. 3

Answer: (A)

To find the value of x in the equation 5x - 5 = 20, the first step is to isolate the term containing x. Start by adding 5 to both sides of the equation to eliminate the -5: 5x - 5 + 5 = 20 + 5, which simplifies to 5x = 25. Next, to solve for x, divide both sides of the equation by 5: 5x / 5 = 25 / 5, resulting in x = 5. This step-by-step manipulation of the equation confirms that the correct value of x is indeed 5. The method shows a clear application of algebraic principles, demonstrating how to rearrange and simplify an equation to isolate a variable.
