any answers? explain too please

4x° + 3° + 2x° + 9° = 180°
(4x + 2x)° + (3 + 9)° = 180°
6x° + 12° = 180°
6x° = 180° - 12°
6x° = 168°
x° = 168/6
x° = 28°
So, the value of x is 28°
Hope it helpful and useful :)
Answer:
x=28
Step-by-step explanation:
1. 4x+3+2x+9=180, Imagine a half circle which is 180 degrees where the image is! if you add the 2 equations, you would get 180
2. Add like terms, 6x+12=180
3. 6x=168, then divide 168 by 6
4. x=28
sorry if this is a bad explanation!
