The value of Y would be -5 = 2y
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
   = x²(-3 +5) +y²(2 -3) +5xy -2y
   = 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
 
        
             
        
        
        
204 /6 = 34
29 +31 +33 + 35 +37 +39 = 207
4th number = 35
