Question

When she subtracts 4 from both sides, 1/2x = -1/2x
results. What is the value of x?

Answer 1

Answer: 0

Explanation:

1/2x = -1/2x cannot be true for any other value of x except when x equals 0. In other words, we need the left and right sides to equal each other, but that would only happen when x=0.
