Solve using substitution. Write the solution in the box as an ordered pair.
3. -3x + 3y = 4
4. x = y + 4
y=x+3
2x +y = 5
Solve using elimination. Write the solution in the box as an ordered pair.
5. 7x + 2y = 24
6. -2x + 3y = 15
-8x – 2y = -30
-6x + 6y = 18
Solve using the method of your choice. Write the solution in the box as an ordered pair.
7. 4x + 2y = 10
8. 6x – 2y = 10
x – y = 13
y = 3x – 5

11. Set up the following system of equations.
(DO NOT SOLVE.)
On the first day of ticket sales a school sold 3 senior
citizen tickets and 1 child ticket for a total of \$38.
The school took in \$52 on the second day by selling
3 senior citizen tickets and 2 child tickets. Find the
price of a senior citizen ticket and the price of a
child ticket.

12. Set up the following system of equations.
(DO NOT SOLVE.)
Leo and Evan complete 45 Algebra problems
together. Evan slacked off and completed 2 less
than half of what Leo completed. Set up the
systems of equations used to solve how much each
one completed.
13. Which of the following ordered pairs is a solution to the system?
y = 4x – 1
2x + y = 5
a) (0, -1)
b) (2, 7)
