Answer:
Let the greater no. = x
Let the lesser no. = y
so, x-y=5
5y-x=9
& go from there by solving the two equations together.
An equivalent equation solved for y is y = a/πx.
Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse.
To find an equivalent equation:
Simplifying,
a = πxy
y = a/πx
Therefore, the equation is y = a/πx

The complete question:
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?
Answer:
We have the formula for determing the area of an ellipse : a = Pi * x * y, and we have to find the equivalent equation solved for y. In this formula x is half the length of the largest and y is half the length of the smallest diameter of the ellipse. Pi is approx. 3.14. Starting with: a = Pi * x * y ( we will divide both sides of the equation by: Pi * x ) => a /(Pi*x) = y. Answer: y = a / (Pi*x).
