Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
9 x + 3 y = 5 .............1
1 y = 1.67 -3 x ---------2
/ 1 =
y = 1.67 -3 x
Substitute y in (1)
9x+3(1.67-3x)= 5
9x+5+-9 x=5
9x-9x=5 -5
0x=0
There is no solution to this system
they are parallel lines with different y intercepts slopes are same
