It seems like you're providing the equation \(2x + 2y = 18\). If you'd like to solve for one variable in terms of the other, simplify the equation, or graph it, please specify!
For example, to simplify the equation, you can divide all terms by 2:
\[ x + y = 9 \]
If you want to solve for \(y\) in terms of \(x\):
\[ y = 9 - x \]
Let me know how you'd like to proceed!
