Which of the following equations has a different value of x than the others?(1 point)
a. x + 9/8 = 7/4
b. x + .875= 1.5
c. x-0.025 = 0.6
d. x - 7/8 = -3/2
To find which equation has a different value of x, we need to solve each equation for x and compare the values.
a. x + 9/8 = 7/4
Subtract 9/8 from both sides:
x = 7/4 - 9/8
x = 14/8 - 9/8
x = 5/8
b. x + .875 = 1.5
Subtract .875 from both sides:
x = 1.5 - .875
x = .625
c. x - 0.025 = 0.6
Add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
d. x - 7/8 = -3/2
Add 7/8 to both sides:
x = -3/2 + 7/8
Using a common denominator of 8:
x = -12/8 + 7/8
x = -5/8
Comparing the values of x for each equation:
a. 5/8
b. 0.625
c. 0.625
d. -5/8
The equation with a different value of x is option a, x + 9/8 = 7/4.
