Which of the following equations has a different value of x than the others?
x+9/8=7/4
x-7/8=-2/8
x+0.875=1.5
x-0.025=0.6
To determine which equation has a different value of x than the others, we can solve each equation and compare the values of x.
1) x + 9/8 = 7/4
To solve for x, we subtract 9/8 from both sides:
x = 7/4 - 9/8
x = 14/8 - 9/8
x = 5/8
2) x - 7/8 = -2/8
To solve for x, we add 7/8 to both sides:
x = -2/8 + 7/8
x = 5/8
3) x + 0.875 = 1.5
To solve for x, we subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
4) x - 0.025 = 0.6
To solve for x, we add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
Comparing the values of x from each equation, we see that equations 3) and 4) both have the same value of x, 0.625. Therefore, the equation that has a different value of x than the others is equation 1) x + 9/8 = 7/4, which has x = 5/8.
