$\angle LMN\ $ is a straight angle. Find $m\angle LMP$ and $m\angle NMP$ .

Three rays, ray M L, M P, and M N begin from a common point, M. The three rays form linear angles. The measure of angle L M P is left-parenthesis negative 16 x plus 13 right-parenthesis, degrees and the measure of angle N M P is left-parenthesis negative 20 x plus 23 right-parenthesis degrees.
