Answer:
x = 5
Step-by-step explanation:
-2x + 13 = -7x + 28
Subtract 13 on both sides
-2x + 13 - 13 = -7x + 28 - 13
-2x = -7x + 15
Add 7x on both sides
-2x + 7x = -7x + 7x + 15
5x = 15
Divide by 5 on both sides to isolate the variable
5x/5 = 15/5
x = 5

Answer:
(√2 − √6) / 4
Step-by-step explanation:
Rewrite using special angles.
sin(-11π/12)
sin((4−15)π/12)
sin(4π/12 − 15π/12)
sin(π/3 − 5π/4)
Use angle difference formula:
sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)
Evaluate:
(√3/2) (-√2/2) − (-√2/2) (1/2)
-√6/4 + √2/4
(√2 − √6) / 4
