?(1 point)
Responses

x − 12 = 1
x minus Start Fraction 1 over 2 End Fraction equals 1

x + 12 = −1
x plus Start Fraction 1 over 2 End Fraction equals negative 1

x − 1 = −12
x minus 1 equals negative Start Fraction 1 over 2 End Fraction

x + 1 = 12

Answer 1

The formatting is a little unclear — could you confirm the four equations exactly? From what I can read the distinct equations look like:

1) x − 12 = 1 → plug in x = −12: −12 − 12 = −24 ≠ 1
2) x + 12 = −1 → −12 + 12 = 0 ≠ −1
3) x − 1 = −12 → −12 − 1 = −13 ≠ −12
4) x + 1 = 12 → −12 + 1 = −11 ≠ 12

So none of those four has −12 as a solution. If any of the options were meant to involve 1/2 or −1/2 instead, please paste the exact equations and I’ll check again.
