Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
 
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
 
        
                    
             
        
        
        
FOR Y 
opposite angles - equal 
angles in a quadrilateral are 360 degrees 
68 + 68 = 136 
360 - 136 = 224
224/2 = 112 degrees
angles on a straight line = 180 degrees 
180 - 112 = 68 
Y = 68
FOR X 
angles on a straight line are 180 degrees 
180 - 68 = 112 degrees
X=112 degrees
        
             
        
        
        
Step-by-step explanation:
Since the polygon has four vertices (D,E,F and G), it is a quadrilateral (4 vertices).
