Can you assist me on solving this problem or advising how to get the end number?

f(x)=g(x) 7x+6=3x-18  What you'll do next is transpose 3x and 6  7x-3x=-18-6  (they become negative because when you transpose you have to change signs. Which means if the number is positive, you change it to negative, and vise versa)  4x=-24   Then divide both sides by 4.   The final answer is. X = -6

hope it you

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
