Question 430099
-15x+3y=6
y=2+5x
----
Substitute for "y" and solve for "x":
---
-15x + 3(2+5x) = 6
-15x+6+15x = 6
6 = 6
-----
That means x can take any value.
The solution is the set of points (x, 2+5x)
---
It means the two equations are really the same equation.
It means the system of equations is dependent.
It means the graph of the two equations only gives
you one line.
