What equation has a different value of x
x + 9/8 = 7/4
x − 0.025 = 0.6
x − 7/8 = −3/2
x + 0.875 = 1.5 explanation
The first equation is:
x + 9/8 = 7/4
To solve for x, we subtract 9/8 from both sides:
x = 7/4 - 9/8
Find a common denominator, which is 8:
x = 14/8 - 9/8
Combine the numerators:
x = 5/8
So the value of x for this equation is 5/8.
The second equation is:
x - 0.025 = 0.6
To solve for x, we add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
So the value of x for this equation is 0.625.
The third equation is:
x - 7/8 = -3/2
To solve for x, we add 7/8 to both sides:
x = -3/2 + 7/8
Find a common denominator, which is 8:
x = -12/8 + 7/8
Combine the numerators:
x = -5/8
So the value of x for this equation is -5/8.
The fourth equation is:
x + 0.875 = 1.5
To solve for x, we subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
So the value of x for this equation is 0.625.
Therefore, the equation that has a different value of x is:
x - 7/8 = -3/2, which has a value of x = -5/8.
