Question 61608: Last graph problem today. This time, my lines run on top of each other.
Solve by graphing and give solution for X and Y
3X+2Y=8
6X+4Y=16
Equation 1:
3X+2(0)=8
3X=8
X=8/3 or 2 2/3 (2 2/3, 0)
3(0)+2Y=8
2Y=8
Y=8/2 or 4 (0,4)
Equation 2:
6X+4(0)=16
6X=16
X=16/6 or 8/3 or 2 2/3 (2 2/3,0)
6(0)+4Y=16
4Y=16
Y=4 (0,4)
As I said, the lines run on top of each other so I cannot determine X and Y.
