To solve the equation \((6x + 3)° + (x - 6)°\), we first clarify that the expression seems to be describing a sum of angles in degrees. However, it's unclear exactly what we are supposed to set this equal to since there is no right-hand side provided.
If this expression is simply an addition of angles, we can combine the two angle expressions algebraically:
\[ (6x + 3) + (x - 6) = 6x + 3 + x - 6 \] Combine like terms:
\[ 6x + x + 3 - 6 = 7x - 3 \]
Thus, the simplified expression is: \[ (7x - 3)° \]
If you have a specific value or equality to set these expressions equal to, please provide that for further assistance! If this is all that's needed, then the result is \( (7x - 3)° \).
