x − 1/2 = 1
x minus Start Fraction 1 over 2 End Fraction equals 1

x + 1/2 = −1
x plus Start Fraction 1 over 2 End Fraction equals negative 1

x − 1 = −1/2
x minus 1 equals negative Start Fraction 1 over 2 End Fraction

x + 1 = 1/2
x plus 1 equals Start Fraction 1 over 2 End Fraction

1 answer

To determine which of the given equations has a solution of x=12, we can substitute 12 into each equation and check if it holds true.

  1. Equation: x12=1
    1212=1
    12.51 (Not a solution)

  2. Equation: x+12=1
    12+12=1
    11.51 (Not a solution)

  3. Equation: x1=12
    121=12
    130.5 (Not a solution)

  4. Equation: x+1=12
    12+1=12
    110.5 (Not a solution)

Since none of the equations hold true for x=12, none of the options provided have a solution of 12.
