Step-by-step explanation:
2x+10=86+x
2x-x=86-10
x=76
I hope you understood :)
 
        
                    
             
        
        
        
-99 = -9*11
176 = 16*11
Both factorizations have 11 show up. It turns out that 11 is the largest common factor. 
Answer: C) 11
Note: if you divide both numerator and denominator by 11, then the fraction reduces to -9/16
