Question 395634
Solve by substitution. indicate whether the system is independent, dependent or inconsistent.
--- 
2x - 3y = 12
3y - 2x = -12
----
x = (12+3y)/2
----
Substitute for "x" and solve for "y":
3y - 2[(12+3y)/2] = -12
---
3y -(12+3y) = -12
--
3y-12-3y = -12
-12 = -12
0 = 0
----
The system is true for all Real Number values of y.
---
The system is dependent.
Each equation is a multiple of the other.
