To find the value of x, we can solve each equation:
1. x-7/8=-3/2
Adding 7/8 to both sides:
x = -3/2 + 7/8 = -12/8 + 7/8 = -5/8
2. x+0.875=1.5
Subtracting 0.875 from both sides:
x = 1.5 - 0.875 = 0.625
3. x+9/8=7/4
Subtracting 9/8 from both sides:
x = 7/4 - 9/8
To subtract fractions, we need a common denominator. The least common multiple of 4 and 8 is 8.
x = (14/8 - 9/8) = 5/8
4. x-0.025=0.6
Adding 0.025 to both sides:
x = 0.6 + 0.025 = 0.625
Comparing the values of x from each equation, we can see that the equation x + 0.875 = 1.5 (equation 2) has a different value of x than the others.
