The answer is 3 
if you substitute x as 4 then it would be 2 x 4 = 8 
8-5=3
        
                    
             
        
        
        
Yo sup??
in the given figure
9y-3=69
9y=72
y=8
now by angle sum property
9y-3+69+5x+2=180
5x=40
x=8
Hope this helps

Answer:
A
Step-by-step explanation:
Just put x = 80 and y = 210 into the equation...
or put x = 40, y = 90. 
A:
210 - 90 = 3(80-40)
120 = 120√
B:
210 + 90 = 3(80+40)
300 = 360×
C:
210 - 90 = 2.6(80-40)
120 = 104×
D:
210 + 90 = 2.6(80+40)
300 = 312×
