The equation sec x = −0.5 does NOT have a solution because

a. the equation is not well formulated

b. of the negative value on the right side

c. it means that sin x = −2 which is outside the range

d. it means that cos x = −2 which is outside the range

given sec x = -1/2

then cos x = -2, which is not possible, you should know that cosine as well as sine fall between -1 and +1
