Let 
be the price of an adult ticket, and 
the price of a child ticket.
The sentence "Three adults and four children must pay $122 for tickets" translates to 
The sentence "Two adults and three children must pay $87" translates to 
Which leads to the linear system
You can solve this system as you prefer, for example you can multiply the first equation by 2 and the second by 3 to get
Now subtract the first from the second:
Now plug this value for c in any of the equations, for example the first:
The Answer To Your Question Would Be 12
Answer:
Step-by-step explanation:
( - 2 , 3 )
( 3 , - 4 )
m = 
= - 
y - 3 = - ( x - ( - 2 ) )
y = - x - 
+ 3
y = - x + 
Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
<em>subtract 4x from both sides of the equation</em>
6x - 4x -8 = 4x - 4x
2x - 8 = 0
<em>add 8 to both sides of the equation</em>
2x - 8 + 8 = 0 + 8
2x = 8
<em>divide both sides of the equation by 2</em>
2x/2 = 8/2
x = 4
