x = 8 - 4y
8 - 4y - 4y = -8
-8y = -16
y = 2
-x-4y= -8
-x -8 = -8
two systems of equations are giving below for each system choosethe best description of its solution if applicable give solution
x+4y=8
-x-4y= -8
choose which one this problem fit in
1)the system has no solution
2) the system has a unique solution (x,y)=
or the system has a infinitely many solutions they must satisfy the following equation: y=

for some reason when I am adding the two equations, I am getting 0 = 0. This is a true statement which means that there is an infinite number of solutions. Any x,y pair that works in one will work in the other.
You're right, Dr. Jane. I hadn't intended to post my answer -- but I guess my finger slipped.
