2) Lakita and Tanisha are writing a short skit for theater class. Tanisha has 1 less than twice the number of lines of dialogue that Lakita has. Together they have 13 lines of dialogue. Which system can be used to find l, the number of dialogue lines Lakita has, and t the number of dialogue lines Tanisha has?

A. l + t = 13 C l + t = 13 t = 2l – 1 t = 2l + 1

B l + t = 13 D l + t = 13 l = 2t – 1 t = 1 – 2l

Discuss “why” you picked that answer.
