Hi there! Yes, x = 2 is a solution to this equation.
Let's solve this equation step by step!
![- 4x + 2 = - 6](https://tex.z-dn.net/?f=%20-%204x%20%2B%202%20%3D%20%20-%206)
Subtract 2 from both sides.
![- 4x + 2 - 2 = - 6 - 2 \\ - 4x = - 8](https://tex.z-dn.net/?f=%20-%204x%20%2B%202%20-%202%20%3D%20%20-%206%20-%202%20%5C%5C%20%20-%204x%20%3D%20%20-%208)
Now divide both sides of the equation by -4 (and remember that when dividing two negatives we end up with a positive).
![x = \frac{ - 8}{ - 4} = 2](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%208%7D%7B%20-%204%7D%20%20%3D%202)
And therefore x = 2 is a solution to this equation.
