To fill in the blanks in the equation \(4x + 10 = _x + _\), we can choose numbers that will create a valid equation. One possible solution could be:
\(4x + 10 = 4x + 10\)
So, the filled equation would be:
\(4x + 10 = 4x + 10\)
If you have specific numbers in mind for the blanks or a different style of equation, please share, and I can adjust the answer accordingly!
