Answer:

x = $\frac{13}{2}$

Step-by-step explanation:

distribute parenthesis on both sides of the equation

6x - 9 = 4x + 4 ( subtract 4x from both sides )

2x - 9 = 4 ( add 9 to both sides )

2x = 13 ( divide both sides by 2 )

x = $\frac{13}{2}$

Answer:

Step-by-step explanation:

$\cos x+\sqrt{2}=-\cos x \\ 2\cos x = -\sqrt 2 \\ \cos x = -\dfrac{\sqrt 2}{2}\\ \\ \Rightarrow x = \pm \arccos\Big(-\dfrac{\sqrt 2}{2}\Big)+2k\pi,\quad x\in \mathbb{Z}\\ \Rightarrow x =\pm\dfrac{3\pi}{4}+2k\pi\\ \\ \\k = -1 \Rightarrow x < 0\\\\ k=0 \Rightarrow x 2\pi$
