You're meant to make one side of the equation equal 0.
For example, the first problem is

+ 9k = -7
You'd add 7 to both sides, leaving you with

+ 9k +7 =0
And I assume you know how to factor??
Hmmm
that's a toughy not sure maybe the last one....
This is not possible because arcsin is the angle that will give you a sine value of 2. Sine values range from -1 to 1; there is no angle that will give you a sine of 2.
