x + x + 1 + x + 2 + x + 3 = 130
Combine like terms.
4x + 6 = 130
Subtract 6 from both sides.
4x = 124
Divide both sides by 4.
x = 31

Answer:
Step-by-step explanation:
cos (2α)*sin (α-β)-cos(β-α)*sin(2α)
cos (β-α)=cos {-(α-β)}=cos (α-β)
[cos (-x)=cos x]
sin(α-β)*cos (2α)-cos (α-β)*sin (2α)=sin (α-β-2α)=sin (-α-β)
=sin {-(α+β)}
=-sin (α+β)
