Y= 7x - 7z -9
+9 +9 Y+9+7z /7=x
Y+9 = 7x - 7z
+7z +7z
Y+9+7z = 7x
/7 /7

Answer:
84 adult tickets and 33 child tickets were sold.
Step-by-step explanation:
Given that a school sold 51 less children's tickets than adult tickets for the school play, and adult tickets cost $ 1.25 and children's tickets cost $ 0.75, and a total of $ 129.75 was taken in, to determine how many of each kind were sold the following calculations must be done:
61 x 1.25 + 10 x 0.75 = 83.75
81 x 1.25 + 30 x 0.75 = 123.75
82 x 1.25 + 31 x 0.75 = 125.75
83 x 1.25 + 32 x 0.75 = 127.75
84 x 1.25 + 33 x 0.75 = 129.75
Thus, 84 adult tickets and 33 child tickets were sold.
