What is STANG
The solution to the following system:
y = x + 4
y = 2x + 5
What is (-1, 3)
The solution to the system of equations:
x + y = -6
x - y = -10
What is (-8, 2)?
x = 4y
2x + 3y = 22
When plugging your x-value back in to solve for your y-value, does it matter which of the original equations we use?
NO!
y = 3x - 2
y = -x - 2
The solution to the system:
8x + 5y =18
2x - 5y = -8
What is (1, 2)?
y = x - 2
3x - y = 16
What did Ms. Stang say was the most common mistake when solving by elimination?
Forgetting to distribute to each term when multiplying to manipulate an equation.
The answer to an equation or system of equations.
What is a solution?
y = (1/3)x - 3
2x - y = 8
The solution to the system
2x - 4y = 12
-8x + 16y = -48
What is infinitely many solutions?
The solution to the system
3x - 2y = 4
x = 2y +8
What is (-2, -5)
How can I check my final solution to ensure I am correct?
Plug my values back into BOTH original equations.
y = -3
x = 5
The solution to the system:
x + y =-3
8x -5y = 2
What is (-1, -2)?
y = 3x - 1
7x + 2y = 37
Name an equivalent equation to the following:
2x+3y=9
Answers may vary
y - 3x = 3
y = 3x - 2
The solution to the system:
4x - 3y =-5
3x +4y = 15
What is (1, 3)
The solution to the system
x + 2y = 14
2y = x-10
What is (12, 1)?
How should your solution to a system of equations be written?
An ordered pair
