two systems of equations are giving below for each system choosethe best description of its solution if applicable give solution
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=
x = 8 - 4y
8 - 4y - 4y = -8
-8y = -16
y = 2
-x -8 = -8
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.
