Step-by-step explanation:
to work out gradient 
change in y ÷ change in x 
first lines gradient
(7 - - 8) ÷ (7 - 7) = 0
second lines gradient
(7 - 7) ÷ (9 - - 6) = 0

Cross multiplying,
 
 
        
             
        
        
        
        
72, 96, 84, 12
72 + (7x+24) = 180
7x + 96 = 180
7x = 84
x = 12
