anonymous · Answer

if you multiply the second one by $-3$ you get the first one  (almost)

anonymous · Answer

$$3x-9y=0\
3x-9y=9$$ the left hand sides are identical, the right hand is different
so you cannot solve this

anonymous · Answer

why do you say it's 1? can you give us your thought process behind that answer.

anonymous · Answer

im confused? how can you tell how many answers it has

anonymous · Answer

well answer is a unique value for both x and y expressed as a point (x,y) where both the x and y values are true if plugged in into either equation.
