$\boxed{ \bold{ \blue{ - 1}}}$

Option B is the correct option.

Step-by-step explanation:

$\mathsf{x + x + 2 + 2x = - 2}$

Collect like terms

$\mathsf{4x + 2 = - 2}$

Move constant to R.H.S and change its sign

$\mathsf{4x = - 2 - 2}$

Calculate

$\mathsf{4x = - 4}$

Divide both sides of the equation by 4

$\mathsf{ \frac{4x}{4} = \frac{ - 4}{4} }$

Calculate

$\mathsf{x = - 1}$

Hope I helped!

Best regards!
