yes, this is not a trick question

, so yes

Step-by-step explanation:

x+ 3 going to equal x+ 3 is the same as saying x+3 = 3+x which is still the same thing as i learned from algebra in 8th grade and some aspect of it in 7th grade and 6th grade

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
