$\huge \bf༆ Answer ༄$

Let's solve ~

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

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

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

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

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