do you know what Cramer's rule is?? Ever heard of it?

anonymous · Answer

yes i know it but idk how to determine whether its inconsistent or dependent..

anonymous · Answer

Is it 2x + 7 = 8 or
2x + 7y = 8 for the first equation?

anonymous · Answer

it says 7 in the question..

anonymous · Answer

So your equations are
2x + 0y  = 1 
6x + 3y = 24

x=1/2
3 + 3 y =24
3y = 21
y =7

The system is consistent

anonymous · Answer

so its B?
