There are a total of 84 students in a drama club and a yearbook club. The drama club has 16 more students than the yearbook club. How many students are in the drama club? the yearbook club?
now we sub y + 16 in for d in the first equation y + d = 84 y + (y + 16) = 84 2y + 16 = 84 2y = 84 - 16 2y = 68 y = 68/2 y = 34 <=== yearbook club students
d = y + 16 d = 34 + 16 d = 50 <=== drama club students
