Which of the following equations has a solution of −12 ?
A x+1/2=-1
B x-1/2=1
C x-1=-1/2
D x+1=1/2
To find which equation has a solution of -12, we need to substitute -12 for x in each equation and see which one results in a true statement.
A) x + 1/2 = -1
If we substitute -12 for x: -12 + 1/2 = -1
-23/2 does not equal -1, so this equation is not true for x = -12.
B) x - 1/2 = 1
Substituting -12 for x: -12 - 1/2 = 1
-25/2 does not equal 1, so this equation is not true for x = -12.
C) x - 1 = -1/2
Substituting -12 for x: -12 - 1 = -1/2
-13 does not equal -1/2, so this equation is not true for x = -12.
D) x + 1 = 1/2
Substituting -12 for x: -12 + 1 = 1/2
-11 does not equal 1/2, so this equation is not true for x = -12.
None of the given equations have a solution of -12, therefore, the answer is None of the above.
