Which of the following equations has the same solution as the equation x + 1/2 = −1/4? (1 point)

1 answer

To find an equivalent equation, we first need to solve the given equation:

  1. Start with the equation: \[ x + \frac{1}{2} = -\frac{1}{4} \]

  2. Subtract \(\frac{1}{2}\) from both sides to isolate \(x\): \[ x = -\frac{1}{4} - \frac{1}{2} \]

  3. To combine the fractions on the right side, convert \(-\frac{1}{2}\) to have a common denominator of 4: \[ -\frac{1}{2} = -\frac{2}{4} \]

  4. Now substitute that in: \[ x = -\frac{1}{4} - \frac{2}{4} = -\frac{3}{4} \]

Now we know that the solution to the equation \(x + \frac{1}{2} = -\frac{1}{4}\) is \(x = -\frac{3}{4}\).

Next, we can create equivalent equations. Here are a couple of examples:

  1. Adding or subtracting the same number from both sides:

    • \(x + \frac{1}{2} + \frac{3}{4} = -\frac{1}{4} + \frac{3}{4}\) simplifies to \(x + \frac{5}{4} = \frac{1}{2}\).
  2. Multiplying or dividing both sides by the same non-zero number:

    • \(2(x + \frac{1}{2}) = 2(-\frac{1}{4})\) simplifies to \(2x + 1 = -\frac{1}{2}\).

Any of these equations, or others formed in similar ways, would share the same solution \(x = -\frac{3}{4}\).

If you provide specific options, I could help identify which one of those maintains the same solution.
