Answer:
x=15 and y= -18
Step-by-step explanation:
Equation 1
Equation 2
From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.
Solving equation 1
Finding 'y' in terms of 'x'
Equation 3
Putting above equation in equation 3 in 2



Putting value of 'x' in equation 3 to find the value of 'y'

Answer:
The equation of a vertical ellipse is 
Step-by-step explanation:
Here, given:
Length of major axis: 20
⇒ 2 a = 20 , or , a = 10
Length of minor axis: 12
⇒ 2 b = 12 , or , b = 6
Also, center (h,k) = (6,3)
Now, STANDARD EQUATION OF ELLIPSE :

Now, substituting the values, a, b , h and k in above expression, we get:

or, 
Hence, the equation of a vertical ellipse is
