?(1 point)
Responses

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

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

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

x + 1 = 12

Answer 1

None of them.

Check by either plugging in x = −12 or solving for x:

- x − 1 = −12 → x = −11
- x + 12 = −1 → x = −13
- x − 12 = 1 → x = 13
- x + 1 = 12 → x = 11

So no equation has −12 as its solution.
