A + S=120
6A +4S = 600
Use substitution A= 120-S
6(120-S) + 4s = 600
720 -6S + 4S = 600
720 -2S = 600

a = numbers of adults
s = number of students
120 people attended the baseball game mean:
a + s = 120
Adults cost $6 and students cost $4 to attend the game.
The game raised $600 from the attendance mean:
a * &6 + s * $4 = $600
OR
6 a + 4 s = 600
Now you must solwe system:
a + s = 120
6 a + 4 s = 600
Try to solve this system.
The solutions are:
a = 60 , s = 60
Proof:
a + s = 60 + 60 = 120
6 a + 4 s = 6 * 60 + 4 * 60 = 360 + 240 = 600
s = number of students
