True
This is because in elimination reaction more bonds break as compared to substitution reaction and require high amount of heat energy. On increasing temperature , it will allow more molecules to reach the required activation energy threshold.
So at higher temperature elimination reaction favored and substitution reaction favored at lower temperature.

All things being equal, high temperatures will favor elimination when substitution and elimination reactions are possible....
