Answer:

Step-by-step explanation:
Since the foci are at(0,±c) = (0,±63) and vertices (0,±a) = (0,±91), the major axis is the y- axis. So, we have the equation in the form (with center at the origin)  .
.
We find the co-vertices b from b = ±√(a² - c²) where a = 91 and c = 63
b = ±√(a² - c²) 
= ±√(91² - 63²) 
= ±√(8281 - 3969) 
= ±√4312 
= ±14√22
So the equation is 

 
        
             
        
        
        
I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:
2(3x + 1) = 11        Divide by 2 on both sides
3x + 1 =  [11/2 or 5.5] Subtract by 1 on both sides
        [11/2 or 5.5] Subtract by 1 on both sides
 [make the denominator the same to combine fractions]
            [make the denominator the same to combine fractions]
3x =  Divide by 3 on both sides
        Divide by 3 on both sides
x =
