Three more than the product of -4 and a number is equivalent to 7 less that number ?in number

3 + (-4n) = 7 - n

Step-by-step explanation: Let the "number" be equal to n.

The equation above represents this situation because it states that 3 + (-4n) is equal to or equivalent to 7 - n.

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
