There exist an abbreviation that ALL - S - T - C where all trigonometric functions in first quandrant are positive. S, T, and C are the first letters of the trigonometric functions that are positive in quadrant 2, 3, and 4, respectively. This also means that in the same quadrant, their reciprocals are also positive. For the given above, it is in Quadrant 3 where T is positive and cosine is negative. 
        
                    
             
        
        
        
Answer:
Looking at the question and goin step by step 
we get to know that equation formed wud be ->
product of nine and a number - 9*x = 9x
added to 6 => 9x+6
gives us 24 
so 
9x + 6 = 24
now 9x = 18 and x = 18/9 = 2 
and now keeping x value = 9 *(2)+6 we get 18+6 = 24 
so lhs = rhs = 24
9x+6=24 option a
