Step-by-step explanation:
they may think about it how they see it. Not 1001 but instead 100(and)1.
 
        
             
        
        
        
The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20

The best way for him to check his answer would be to simply plug in the value found for x into the equation. 
4(2) - 6 = 2
8 - 6 = 2
2 = 2
