Answer16
Step-by-step explanation:
So the total number of movie tickets sold was 1200. This means that a + c = 1200 because a represents the number of adult tickets purchased and c represents the number of child tickets purchased. The total money they made off the movie was $6400. This means 7 multiplied by the number of adult tickets would result in the total they earned off adult tickets, and 3 multiplied by the number of child tickets would result in the total they earned off child tickets. This total equals 6400. So 7a + 3c = 6400. These are our two equations: a + c = 1200 and 7a + 3c = 6400. The answer choice that matches this is choice A, so your answer is A. Hope this helps.

7x + 3y = -9
+9 +9
________________
7x + 3y + 9 = 0
-3y -3y
_______________
7x + 9 = -3y
(divide each side by negative 3)
7x 9
__ + __ = y
-3 -3
simplified it would be :
7x
__ - 3 = y
-3
