Which of the following equations has a different value of x than the others?
A. x+9/8=7/4
B. x-7/8= -3/2
C. x -0.025=0.6
D. x +0.875=1.5
To find the value of x in each equation, we need to isolate x by manipulating the equation.
A. x + 9/8 = 7/4
Subtract 9/8 from both sides:
x = 7/4 - 9/8
x = 28/8 - 9/8
x = 19/8
B. x - 7/8 = -3/2
Add 7/8 to both sides:
x = -3/2 + 7/8
x = -12/8 + 7/8
x = -5/8
C. x - 0.025 = 0.6
Add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
D. x + 0.875 = 1.5
Subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
Looking at the values we found, we can see that option B has a different value for x than the others. The correct answer is B.
