Which of the following equations has a different value of X than the others. (1 point)

A. x − 78 = −32

B. x + 0.875 = 1.5

C. x − 0.025 = 0.6

D. x + 98 = 74

1 answer

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

A. \( x - 78 = -32 \)
To solve for \( x \), we add 78 to both sides:
\( x = -32 + 78 \)
\( x = 46 \)

B. \( x + 0.875 = 1.5 \)
To solve for \( x \), we subtract 0.875 from both sides:
\( x = 1.5 - 0.875 \)
\( x = 0.625 \)

C. \( x - 0.025 = 0.6 \)
To solve for \( x \), we add 0.025 to both sides:
\( x = 0.6 + 0.025 \)
\( x = 0.625 \)

D. \( x + 98 = 74 \)
To solve for \( x \), we subtract 98 from both sides:
\( x = 74 - 98 \)
\( x = -24 \)

Now we have the values:

  • A: \( x = 46 \)
  • B: \( x = 0.625 \)
  • C: \( x = 0.625 \)
  • D: \( x = -24 \)

The equation with a different value of \( x \) than the others is D.
