`cos3x + sin(2x- (7pi)/6)=-2`

Find x cos3x+sin(2x-(7 pi)/(6))=-2

If cos 3x+sin (2x-(7pi)/6)=-2 , then x is equal to (k in Z)

If cos 3x+sin (2x-(7pi)/6)=-2 , then x is equal to (k in Z)

If cos3x+sin(2x-(7 pi)/(6))=-2, then x is equal to (k in Z)(pi)/(3)(6k+1)( b) (pi)/(3)(6k-1)(pi)/(3)(2k+1)( d ) none of these

If "cos 3x + "sin" (2x - (7pi)/(6)) =-2 , then x =

If "cos 3x + "sin" (2x - (7pi)/(6)) =-2 , then x =

If cos 3 x + sin (2 x - (7 pi)/(6)) = - 2 then x is equal to (k in Z)

The number of solution for , {:(sin(x-(pi)/4)-cos(x+(3pi)/4)=1),(" "(2cos 7x)/(cos 3+sin3) gt 2^(cos 2x)):}}" in" (0,2pi) is
