zzr0ck3r · Answer

can you solve the system?

zzr0ck3r · Answer

you either get 1, none, or infinite solutions

zzr0ck3r · Answer

1 implies intersecting, infinite implies they are the same, 0 implies they have the same slope but never touch

So is it coincident?

anonymous · Answer

the second equation is $-4x +y = -3 \Longleftrightarrow -12x + 3y = -12 \Longleftrightarrow 12x - 3y = 12 $.

these equations can have solutions in a universe where $9 = 12.$
