4x 4 9x+6

It looks like you have an expression that may need simplification or solving. However, the way it is written is not clear.

If you meant the expression \(4x + 4 + 9x + 6\), you can combine like terms:

1. Combine the \(x\) terms: \(4x + 9x = 13x\).
2. Combine the constant terms: \(4 + 6 = 10\).

So, the expression simplifies to:

\[ 13x + 10 \]

If this isn't what you intended, please clarify what you would like to do with the expression!
