X = number of adult tickets
7x = value of the adult tickets
3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x
Value of adults plus value of children's = 6000
7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets
Number of children's tickets = 3 * 375 = 1125 = number of children's tickets
Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000
The mean to this question is 87.875
I believe it would be 13+13+13+13=52 because all side of a square are equal
Answer:

Step-by-step explanation:
First subtract 2x on both sides. and you'll have x+5=-7.
Second subtract 5 on both sides, it will equal you x=-12
