Answer:
The correct answer is E: None of these.
Explanation:
solve the equation step by step:
X/2 - 7/10 = X/5 - 5/2
First, let's get rid of the fractions by finding a common denominator, which is 10:
5(X/2) - 7 = 2(X/5) - 25/2
Now, multiply both sides of the equation by 10 to eliminate the fractions:
5(X) - 70 = 2(2X) - 25
Now, simplify both sides:
5X - 70 = 4X - 25
Next, let's isolate the variable X on one side by moving the 4X from the right side to the left side by subtracting 4X from both sides:
5X - 4X - 70 = -25
This simplifies to:
X - 70 = -25
Now, add 70 to both sides to isolate X:
X - 70 + 70 = -25 + 70
X = 45
So, the correct answer is:
X = 45
Therefore, none of the provided answer choices (A, B, C, D) is correct. The correct answer is E: None of these.
