Question

Which of the following equations has a solution of −12
?(1 point)
Responses

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

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

Answer 1

None of them.

Check by solving each:
- x + 1 = 12 → x = 11
- x − 12 = 1 → x = 13
- x + 12 = −1 → x = −13
- x − 1 = −12 → x = −11

None of these solutions is −12 (or substitute x = −12 into each and none of the equations is true).
