Question 591917: solve using the sustition method show work if system has no solution or an infinite number of solution
-8x - 4y +-68
x + 3y = 16
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
-8x - 4y = -68
x + 3y = 16
---
Divide thru the 1st equation by -4 to get:
2x + y = 17
So y = 17-2x
---
Substitute for "y" in the 2nd equation:
x + 3(17-2x) = 16
x + 51 - 6x = 16
-5x = -25
x = 5
----
Solve for "y":
y = 17-2*5
y = 7
