The formula for the sine sum is
So, equation
Cannot be solved with standard ways. However, we can build special cases to make it work.
The most trivial example would be A=B=0. In this case, we have
If we work on this idea a little bit, we can produce examples like
And again we have
So, yes, it is possible that 
, although solving the equation directly would be quite difficult.
Answer:
-5/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(518×11)−(56×33)=?
Complete the multiplication and the equation becomes
518−1518=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
5−1518=−1018
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 18 using
GCF(10,18) = 2
−10÷218÷2=−59
Therefore:
518−56=−59
