Question 201617: Solve the system by substitution
-x-6y=5
x+6y=7
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Solve the system by substitution
-x-6y=5
x+6y=7
----------------
Solve the 1st equation for "x":
x = -6y-5
----
Substitute into the 2nd equation to solve for "y":
-6y-5 + 6y = 7
-5 = 7
----
This is a contradiction.
It means there is no consistency between the x/y values
of the two equations.
It means the graphs of the two equations are parallel.
The system is said to be inconsistent.
The system has no solution.
