Question

check whether the following equations are consistent or inconsistent 2 X + Y - 3 is equal to zero 2 x - 3 Y - 7 is equals to zero

Answer 1

2x +y-3
2x-3y-7
therefore a1=2 a2=2
b1= 1 b2= -3
c1= -3 c2= -7
therefore a1/ a2 is not equal to b1/b2 that means that have exactly one solution
then we know that the equation which have solution is consistent.
so, this equation is consistent
