Answer:
x = -10
Step-by-step explanation:
move all the constants (numbers without variables) to one side to get
-4x = 42 - 2
-4x = 40
multiply by -1
4x = -40
divide by 4
x = -10
 
        
                    
             
        
        
        
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)
To get the interior angles you subtract 180 from 12 to get 168 degrees
        
             
        
        
        
Answer: x= -2
Step-by-step explanation: first step is to add 7 to both sides. You’re left with -6x-22=5x. After this you’re going to add 6 to both sides. You get -22=11x. Now you divide both sides by 11 to get X by itself. You’re left with -2.
