Answer: x= −1/2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−9(x−2)=18x+30

Step 1: Simplify both sides of the equation.

3x−9(x−2)=18x+30

3x+(−9)(x)+(−9)(−2)=18x+30(Distribute)

3x+−9x+18=18x+30

(3x+−9x)+(18)=18x+30(Combine Like Terms)

−6x+18=18x+30

Step 2: Subtract 18x from both sides.

−6x+18−18x=18x+30−18x

−24x+18=30

Step 3: Subtract 18 from both sides.

−24x+18−18=30−18

−24x=12

Step 4: Divide both sides by -24.

−24x

−24

−1

Step-by-step explanation:

2 csc²x-2 csc x-1=0

$\frac{2}{sin^2x} -\frac{2}{sin x} -1=0\\multiply~by~sin^2x\\2-2sin~x-sin^2x=0\\sin^2x+2sinx-2=0\\sin ~x=\frac{-2 \pm\sqrt{2^2-4*1*(-2)} }{2*1} \\=\frac{-2 \pm\sqrt{4+8} }{2} \\=\frac{-2 \pm\sqrt{4*3} }{2} \\=\frac{-2 \pm2\sqrt{3} }{2} \\=-1\pm\sqrt{3} \\|sin~x| \le ~1\\so~sin~x=-1+\sqrt{3} \\sin~x=\sqrt{3} -1\\x=sin^{-1}(\sqrt{3} -1) \approx 47.06^\circ,180-47.06\\or~x=47.06^\circ,132.94^\circ$
