y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
The sum of two numbers is 104. Their difference is 68. What are the numbers?
What are 86 and 18?
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
y = x - 2
3x - y = 16
A shopper bought 6 shirts and 8 hats for $700. A week later, at the same prices, he bought 9 shirts and 6 hats for $660. Write a system of equations to represent the situation.
6s + 8h = 700
9s + 6h = 660 ?
y = -3
x = 5
2x + 3y = 6
3x + 5y = 15
y = 3x - 1
7x + 2y = 37
A science teacher took his class to a museum and paid $512 for 10 adult tickets and 9 children's tickets. The next day, the health teacher took our class to the same museum and paid a total of $831 dollars for 17 children and 15 adults. Write a system of equations that represent the scenario.
What is
10a +9c = 512
15a +17c = 831?
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
3s - 2t = 4
t = 2s - 1
Paul has $20 in his savings account, and he saves $5 dollars each week. George has $15 in his savings account, and he saves $10 each week. Write a system of equations to represent the situation and solve algebraically.
What is (1, 25)?
P= 20 + 5x
G= 15 + 10x
y - 3x = 3
y = 3x - 2
The solution to the system rounded to the nearest whole numbers:
(0.75)x + (0.25)y = 10
(0.15)x - (0.50)y = 4
What is (15, 8)
t + u = 12
t = (1/3)u
Kayla wants to buy 5 times as many pens (p) than notebooks (n).
Pens cost 10 cents and notebooks cost 50 cents and she wants to spend exactly $10.
Write a system of equation to represent the situation.
What is p = 5n and 0.10p + 0.50n = 10 ?
