Reece and Mr. Truman (Team 4 English teacher) have turned to songwriting to deal with their boredom while being shut in. Reece has 15 songs already written and is writing 2 songs per day. Mr. Truman has 6 songs already written, but is writing 5 songs per day. Write and solve a system of equations to figure out many days until both will have written the same number of songs (and how many songs that will be).
