First define the variables:
c = amount of children
a = amount of adults
Next create the equations to satisfy the conditions:
1) Total group is 12 people:

2) Total cost is $100 with adults costing $10 and children being $6:

Answer:
In the last diagram the object is being acted upon by forces not adding up to zero.
Step-by-step explanation:
(Assuming force 1=force 2 in terms of magnitude)
Let forces acting towards the left = -1
Let forces acting toward the right = +1
In the first diagram, force1 is acting towards the left and force2 is acting towards the right:
Total force = force1+force2=-1+1=0
In the second diagram, force1 is acting towards the left and force2 is acting towards the right:
Total force = force1+force2=-1+1=0
In the third diagram, force1 is acting towards the right and force2 is acting towards the left:
Total force = force1+force2=+1-1=0
In the fourth diagram, force1 is acting towards the left and force2 is acting towards the left:
Total force = force1+force2=-1-1=-2. Here, the forces do not add up to zero.

Answer:
If solving for y: y = 8 - 2x
If solving for x: x = 
Step-by-step explanation:
<u>To solve for y:</u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y = 
Simplify
to 8.
2x + y = 8
Subtract 2x from both sides.
y = 8 - 2x
<u>To solve for x: </u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y = 
Simplify
to 8.
2x + y = 8
Subtract y from both sides.
2x = 8 − y
Divide both sides by 2.
x =
