At least how many linear equations will be in a system of linear equations?
At least 2 linear equations
400
What is the solution to the system of linear equations?
y= 2x
y= -2x + 4
(1,2)
400
How would you isolate x in this equation?
5x=20
Divide both sides by 5
400
Use the Elimination method to solve for x:
5x - y = 0
3x + y = 24
y=3

What are the 3 methods for solving systems of linear equations?
Graphing, substitution, and linear combination (elimination)
500
What is the solution to the system of linear equations?
x - y = 3
y = -x + 3
Infinitely many solutions
500
Use the substitution method to solve the system of linear equations:
y=2x
3x+y=20
Solution: (4,8)
500
Use the Elimination method to solve for y:
y + x = 2
2y - x = 1
y = 1
