Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x =  - 4}}}}}

Step-by-step explanation:

\sf{3x - 5 = 2x - 9}

Move 2x to left hand side and change it's sign

⇒\sf{3x - 2x - 5 =  - 9}

Move 5 to right hand side and change it's sign

⇒\sf{3x - 2x =  - 9 + 5}

Collect like terms

⇒\sf{x =  - 9 + 5}

Calculate

⇒\sf{x =  - 4}

Hope I helped!

Best regards!!

Hi there!

\large\boxed{x = \frac{\pi}{3} \text{ and } \pi}

We are given:

cos(7x)cos(4x) = -1 - sin(7x)sin(4x)

Begin by moving all terms with variables to one side:

cos(7x)cos(4x) + sin(7x)sin(4x) = -1

The corresponding trig identity is cos(A - B). Thus:

cos(7x - 4x) = cos(7x)cos(4x) + sin(7x)sin(4x) = -1

cos(3x) = -1

cos = -1 at  π, so:

3x = π

x = π/3

We can also find another solution. Let 3π = -1:

3x = 3π

x = π

Thus, solutions on [0, 2π) are π/3 and π.
