y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
Ms. Partlon took her nieces and nephew to the grocery store and she bought $7.65 worth of artichokes and avocados. Each artichoke costs $1.75 and each avocado costs $0.40. She bought a total of 9 artichokes and avocados altogether. Write a system of equations that could be used to determine the number of artichokes and avocados. Use x and y for your variables.
1.75x + .40y = 7.65
x + y = 9
Joke: What is the best place in your house to do your math homework?
The kitchen! Because of all the COUNTERS!
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
y = x - 2
3x - y = 16
Students can buy tickets to a Neshaminy football game for $1. The admissions for adults is $2. If 350 tickets are sold and the total money made is $450, how many student and adult tickets were purchased?
Equations: s + a = 350
s + 2a = 450
Solutions: a = 100 and s = 250
Joke: Why should we never talk to our irrational friend Pi?
Because he will go on and on forever!!
The solution to the system of equations:

-4x + 2y = 6
What is infinitely many solutions?
2x + 3y = 6
3x + 5y = 15
y = 3x - 1
7x + 2y = 37
A collection of nickels and quarters is worth $12.30. There are 66 coins in all. How many of each type of coin are there?
Equations: .05n + .25q = 12.30
n + q = 66
Solutions: n = 21 and q = 45

You crack me up!
The solution to the system of equations
y = (1/3)x - 3
2x - y = 8
What is (3, -2)
2a - 4b = 12
-8a + 16b = -48
3s - 2t = 4
t = 2s - 1
Jason owns a food truck that sells tacos and burritos. He sells each taco for 4. 75 and each burrito for $7.50. Yesterday Jason made a total of $790 in revenue from all the burrito and tacos sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of burritos sold. Let t = the number of tacos sold and let b = the number of burritos sold.
4.75t + 7.50b = 790 and
b = 2t
What did the zero say to the eight?
Nice belt!
The solution to the system of equations:
y = 3x + 3
y = 3x - 2
What is no solution?
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
t + u = 12
t = (1/3)u
Tim and Allie work at a dry cleaners ironing shirts. Tim can iron 20 shirts per hour, and Allie can iron 25 shirts per hour. Tim worked 4 more hours than Allie and they ironed 350 shirts between them. Determine the number of hours Tim worked and the number of hours Allie worked. Let x = # of hrs Tim worked and let y = the # of hrs Allie worked.
Equations: 20x + 25y = 350
x = y + 4
Solutions: Tim = 10 hrs and Allie = 6 hrs
