Answer: See bolded equations
Step-by-step explanation:
The system of equations can be used to solve this problem. C is child ticket and a is adult ticket.
Equation 1
3c+4a=1740
This equation comes from the cost of the tickets. 3c is the cost of $3 per child ticket and 4a is the cost of $4 per adult ticket. 1740 is the total amount collected.
Equation 2
c+a=530
This comes from the number of tickets sold. The c+a is the total of child and adult tickets sold and 530 is the total amount of tickets.

Step-by-step explanation:
Simplifying
f + -6 = 3f + 1
Reorder the terms:
-6 + f = 3f + 1
Reorder the terms:
-6 + f = 1 + 3f
Solving
-6 + f = 1 + 3f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-3f' to each side of the equation.
-6 + f + -3f = 1 + 3f + -3f
Combine like terms: f + -3f = -2f
-6 + -2f = 1 + 3f + -3f
Combine like terms: 3f + -3f = 0
-6 + -2f = 1 + 0
-6 + -2f = 1
Add '6' to each side of the equation.
-6 + 6 + -2f = 1 + 6
Combine like terms: -6 + 6 = 0
0 + -2f = 1 + 6
-2f = 1 + 6
Combine like terms: 1 + 6 = 7
-2f = 7
Divide each side by '-2'.
f = -3.5
Simplifying
f = -3.5
