Which of the following equations has a different value of x than the others? Which of the following equations has a different value of x than the others?
x + 0.875 = 1.5
x − 7/8 = −3/2
x − 0.025 = 0.6
x + 9/8 = 7/4
To find which equation has a different value of x than the others, we need to solve each equation and compare the values of x.
1) x + 0.875 = 1.5
Subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
2) x − 7/8 = −3/2
Add 7/8 to both sides:
x = -3/2 + 7/8
x = -12/8 + 7/8
x = -5/8
3) x − 0.025 = 0.6
Add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
4) x + 9/8 = 7/4
Subtract 9/8 from both sides:
x = 7/4 - 9/8
x = 14/8 - 9/8
x = 5/8
From our calculations:
- The first equation x = 0.625
- The second equation x = -5/8
- The third equation x = 0.625
- The fourth equation x = 5/8
We can see that the second equation x = -5/8 is different from the others, so the correct answer is:
The equation x − 7/8 = −3/2 has a different value of x than the others.
