Answer:

12x + 6y = 15

-2x = y + 4 --------> 0 = 2x + y + 4 ------> -y = 2x + 4 -------> y= -2x -4

12x + 6 ( -2x - 4 ) = 15

12x -12x - 24 = 15

-24 = 15

No solutions

Step-by-step explanation:

-24 does not equal 15 so this problem has no solutions.

Either sin θ=0

θ=0,π,2π

cosθ-1/2=0

cos θ=1/2=cos π/3,cos(2π-π/3)

θ=π/3,5π/3
