Question 1058868: I need help figuring out the answer and how to get there with Solve by Substitution method;
8y-x=1
-2x+16y=2
Thank You!! Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Solve by Substitution method;
8y-x=1 --> x = 8y - 1
-2x+16y=2
========
-2x+16y=2
Sub for x
-2*(8y-1) + 16y = 2
-16y + 2 + 16y = 2
2 = 2
-------------
--> dependent
The 2nd equation is -2 times the 1st.
1 equation, no unique solution.
