Answer:
immm go with A
Step-by-step explanation:
if im wrong plz tell me
Graph B would be the answer.
3x-2y=12
-2y=-3x+12
y=3/2x-6
2x + 1.5 y = 985
y = students
x = adults
x + y = 578
*-2 * -2
-2x - 2y = -1156
2x + 1.5y = 958
-2x - 2y = -1156 (add these together)
-0.5 y = -198
*-2 *-2
y = 396
x + 396 = 578
x = 182
396 students
182 adults
