Question 514459: Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution.
2x-y=1
3x+y=−3 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution.
2x-y=1
3x+y=−3
----
Rearrange:
y = 2x-1
y = -3x-3
----
The slopes are not the same so the
line graphs would cross at one point.
---
Ans: one solution.
