Question

4x=y-2
4x-y=9

solve the system by the method of your choice.

anonymous · Answer

start with 
$$4x-y=-2$$
$$4x-y=9$$ and then note that you have the same thing on the left but different numbers on the right, so there is no solution

anonymous · Answer

if x=0 then y=2; and if y=0 then x=-1/2. Keep plugging in numbers for either your x or y variables to find different solutions; assuming these are for points along a line (i.e. basic algebra)

can i have a follow-up question..what if it's 0x + 0y = 0? what is that? no solution too? indeterminate? or something? @satellite73

kinggeorge · Answer

@lgbasallote I would call that indeterminate. There are infinitely many solutions, so you can't tell which one to use.

lgbasallote · Answer

oh thank you  :D always got me confused

anonymous · Answer

if you get $$0x+0y=0$$ then it is true for all x and y

anonymous · Answer

i.e. it is the same line
