Step-by-step explanation:
Move 
26
 to the right side of the equation because it does not contain a variable.
3x2−12x−2y2+16y=26
 
        
                    
             
        
        
        
Answer:
 x = -2
And, x = 7 ÷ 2 
Step-by-step explanation:
Given that
y = 2x^2
y = 3x + 14
Now equate these two above equations
2x^2 = 3x + 14
2x^2 - 3x - 14
2x^2 -7x + 4x - 14
x(2x - 7) + 2(2x - 7)
(x + 2) (2x - 7)
So it can be x = -2
And, x = 7 ÷ 2 
 
        
             
        
        
        
-9 + 10 over 4 = -7 
1/4 = -7
1/4 does not equal -7
