(I really need help pl) Translate and solve the following equation: Six times the difference of two and twice a number, increased by three times a number is negative fifteen.

6(2 - 2x) + 3x = -15

12 - 12x + 3x = -15

Combine like terms

-9x + 12 = -15

-12             -12

-9x = -17

/-9    /-9

X = 1.88.. *repeated*

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

(3x-8) or (3x+8)
