Question 152812: use cramers rule or to determine that the system is inconsistent or contains dependent equations:
x-2y=5
5x-y=-2
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
in gral:
ax+by=e
cx+dy=f
if ad-bc is not 0 the system is independent
so
x-2y=5
5x-y=-2
ad-bc=1(-1)-(-2)(5)=9 then the system is independent
