The answer is this hopefully this helped the only thing you need to do is just put the steps so just do - 12÷3 or you can ask somebody to help you to divide.
The answer is
x + y = 7
6.50x + 3.50y = 33.50
x - the number of adult tickets
y - the number of child tickets
<span>Group of 7 people: x + y = 7
</span> 6.50 adults and 3.50 for child ticket cost <span>33.50: 6.50x + 3.50y = 33.50
So, we have two equations:
</span>x + y = 7
6.50x + 3.50y = 33.50
1 = x + 4
3 = x
2 = 2x + 5
3 = 2x
3/2= x
