Answer:
- x = y +10; x +y = 64
- x = 37; y = 27
- 37 in drama club; 27 in yearbook club
Step-by-step explanation:
The equations will reflect the relations given in the problem statement:
x = y +10 . . . . . . 10 more in drama club than yearbook club
x + y = 64 . . . . . total of 64 students in both clubs
__
If we use the first equation to substitute for x in the second equation, we get ...
(y +10) +y = 64
2y = 54 . . . . . . . subtract 10
y = 27 . . . . . . . divide by 2
x = y +10 = 27 +10 = 37
There are 37 students in the drama club; 27 in the yearbook club.
