Which of the following equations has a different value of x than the others?

A. x + 0.875 = 1.5
B. x + 9/8 = 7/4
C. x - 0.025 = 0.6
D. x - 7/8 = - 3/2

1 answer

The equation that has a different value of x than the others is D. x - 7/8 = -3/2.

To solve for x in each equation:

A. x + 0.875 = 1.5
x = 1.5 - 0.875
x = 0.625

B. x + 9/8 = 7/4
x = 7/4 - 9/8
x = 14/8 - 9/8
x = 5/8

C. x - 0.025 = 0.6
x = 0.6 + 0.025
x = 0.625

D. x - 7/8 = -3/2
x = -3/2 + 7/8
x = -12/8 + 7/8
x = -5/8

The value of x in equation D is -5/8, which is different from the value of x in the other equations.
