1 answer

Let's solve each equation to find the value of \( x \):

  1. Equation 1:
    \( x - 78 = -32 \)
    \( x = -32 + 78 \)
    \( x = 46 \)

  2. Equation 2:
    \( x - \frac{7}{8} = -\frac{3}{2} \)
    To solve for \( x \):
    \( x = -\frac{3}{2} + \frac{7}{8} \)
    Convert \( -\frac{3}{2} \) to eight as a common denominator:
    \( -\frac{3}{2} = -\frac{12}{8} \)
    Thus,
    \( x = -\frac{12}{8} + \frac{7}{8} = -\frac{5}{8} \)

  3. Equation 3:
    \( x + 0.875 = 1.5 \)
    \( x = 1.5 - 0.875 \)
    \( x = 0.625 \)

  4. Equation 4:
    \( x + 98 = 74 \)
    \( x = 74 - 98 \)
    \( x = -24 \)

  5. Equation 5:
    \( x - 0.025 = 0.6 \)
    \( x = 0.6 + 0.025 \)
    \( x = 0.625 \)

Now, we have the solutions for each equation:

  • Equation 1: \( x = 46 \)
  • Equation 2: \( x = -\frac{5}{8} \)
  • Equation 3: \( x = 0.625 \)
  • Equation 4: \( x = -24 \)
  • Equation 5: \( x = 0.625 \)

The values for \( x \) are:

  • \( 46 \)
  • \( -\frac{5}{8} \) (which is approximately \( -0.625 \))
  • \( 0.625 \)
  • \( -24 \)

Unique value of \( x \):
The equation with a different \( x \) value is Equation 1 (\( x - 78 = -32 \)) with \( x = 46 \).

Thus, the answer is Equation 1.
