8x+4y=8
-8x+2y=8
You can put this solution on YOUR website! Solve
A) symbolically .
8x+4y=8
-8x+2y=8
-----
Add the 2 equations to get:
6y = 16
y = 8/3
---
Solve for "x":
8x+4y = 8
2x+y = 2
2x + (8/3) = 2
2x = 2- (8/3)
2x = -2/3
x = -1/3
===================
B) graphically
8x+4y=8
-8x+2y=8
-------------
Solve both for "y":
y = -2x+2
y = 4x+4
----
================================================
C) numerically
How is that any different from you A problem?
