Solve for the unknown variable.
19 = 3y - 5

y=8

Step-by-step explanation:

Step 1: Flip the equation.

3y−5=19

Step 2: Add 5 to both sides.

3y−5+5=19+5

3y=24

Step 3: Divide both sides by 3.

3y

3

=

24

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
