If 2x/2y = 23 , then x must be equal to?
Correct answer: A. y+3
- A. y+3
- B. y-3
- C. 3-y
- D. 3y
Explanation
The original equation is 2x/2y = 23. Using the quotient rule for exponents, we have 2x-y = 23. This means that x - y = 3. Solving for x gives us x = y + 3. Therefore, the correct answer is x = y + 3. The other options are incorrect because they do not properly apply the properties of exponents to solve for x given the equation.
