x − 8 = 0
x minus 8 equals 0
x − 4 = −12
x minus 4 equals negative 12
The equation x - 8 = 0 has a solution of -8 because when we substitute -8 for x, we get -8 - 8 = 0.

Which of the following equations has a solution of −1/2 ?(1 point)
Responses
x + 1 = 1/2
x plus 1 equals Start Fraction 1 over 2 End Fraction
x − 1/2 = 1
x minus Start Fraction 1 over 2 End Fraction equals 1
x + 1/2 = −1
x plus Start Fraction 1 over 2 End Fraction equals negative 1
x − 1 = −1/2
Responses
x + 1 = 1/2
x plus 1 equals Start Fraction 1 over 2 End Fraction
x − 1/2 = 1
x minus Start Fraction 1 over 2 End Fraction equals 1
x + 1/2 = −1
x plus Start Fraction 1 over 2 End Fraction equals negative 1
x − 1 = −1/2
The equation x + 1/2 = -1 has a solution of -1/2 because when we substitute -1/2 for x, we get -1/2 + 1/2 = -1.
