Answer 1

`\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`
