Which of the following equations has a solution of −12 ?(1 point) Responses 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 x plus 1 equals Start Fraction 1 over 2 End Fraction x − 12 = 1 (choose one of the asnwers)
The equation that has a solution of -12 is x + 12 = -1.
To determine which of the given equations has a solution of -12, we can substitute -12 for the variable in each equation and find the equation that results in a true statement.
Let's check each equation:
1) x + 12 = -1
Substituting -12 for x:
-12 + 12 = -1
0 = -1
This is not true, so the equation x + 12 = -1 does not have a solution of -12.
2) x + 1/2 = -1
Substituting -12 for x:
-12 + 1/2 = -1
-24/2 + 1/2 = -1
-23/2 ≠ -1
This is not true, so the equation x + 1/2 = -1 does not have a solution of -12.
3) x - 1 = -12
Substituting -12 for x:
-12 - 1 = -12
-13 = -12
This is not true, so the equation x - 1 = -12 does not have a solution of -12.
4) x + 1 = 12
Substituting -12 for x:
-12 + 1 = 12
-11 = 12
This is not true, so the equation x + 1 = 12 does not have a solution of -12.
5) x - 12 = 1
Substituting -12 for x:
-12 - 12 = 1
-24 ≠ 1
This is not true, so the equation x - 12 = 1 does not have a solution of -12.
Therefore, none of the given equations have a solution of -12.
To determine which equation has a solution of -12, we need to check each equation and see if substituting -12 for x results in a true statement.
Let's evaluate each equation one by one:
1) x + 12 = -1
To check if -12 is a solution, we substitute x with -12:
-12 + 12 = -1
0 = -1 (False)
2) x + 1/2 = -1
Substituting x = -12:
-12 + 1/2 = -1
-23.5 = -1 (False)
3) x - 1 = -12
Substituting x = -12:
-12 - 1 = -12
-13 = -12 (False)
4) x + 1 = 12
Substituting x = -12:
-12 + 1 = 12
-11 = 12 (False)
5) x - 12 = 1
Substituting x = -12:
-12 - 12 = 1
-24 = 1 (False)
From the analysis above, none of the given equations have a solution of -12.
