Answer 2

Solution to the Equations

To solve the given equations X^3 + 27Y^3 = 54 and X^2 - 3XY + 9Y^2 = 9, we can use a method called substitution. Let's start by solving for one variable in terms of the other and then substituting that value into the other equation.

First, let's solve the second equation for X in terms of Y: X^2 - 3XY + 9Y^2 = 9

Now, let's solve the first equation for X in terms of Y: X^3 + 27Y^3 = 54

Substitution

We can substitute the value of X from the second equation into the first equation to solve for Y.

After substituting, we can solve for Y and then use the value of Y to find the corresponding value of X.

Let's proceed with the substitution and solving for Y.
