Convert the given equation into an algebraic expression.
The given equation can be converted into an algebraic expression by either isolating the terms with the variables, or by moving all the terms to one side of the equation to make it equal to zero. Here are both of those options:

1. Isolating the terms with the variables:
- We can move the constant term to the right side of the equation, by subtracting 5y from both sides. This results in the algebraic expression:

3x = 9 - 5y

- Alternatively, we can isolate y by moving the terms involving x to the right side of the equation. Subtracting 3x from both sides gives us:

5y = 9 - 3x

2. Moving all the terms to one side to make it equal to zero:
- We can subtract 9 from both sides of equation.

This gives the algebraic expression: 
3x + 5y - 9 = 0. 

Overall, the original equation `3x+5y=9` can be expressed in several different equivalent forms, depending on the specific needs or context.
3x+5y=9
