Problem in transforming one differential equation

I have the following example written: https://docs.google.com/document/d/1KUDzLbOrlCuU6aFnePHrMLepNoSCWRPPjo4CM3_ezy0/edit?usp=sharing

Could someone please help me and solve the following in the same way?

y′′ +(2−sinx)y′ +12y = 0, −1 ≤ x ≤ 7,

y(0) = −2, y′(0) = −1.

Best regards,

N.K.
