\huge \bf༆ Answer ༄

Let's solve ~


{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:7 \sec(x) - 7 = 0


{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:7 \sec(x) = 7


{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \sec(x) = 7 / 7


{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \sec(x) = 1


{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:x = 0
