Question

show that the following pair of equation is inconsistent.
2x + 7y = 11 , 5x+35y/2 = 25.

Answer 1

Heya !!!


2X + 7Y = 11-----------(1)


5X + 35Y/2 = 25

10X + 35Y - 50 = 0--------(2)


These equations are in the form of A1X+B1Y+C1 = 0 and A2X+B2Y+C2 = 0 Where ,


A1 = 2 , B1 = 7 , C1 = -11


And,


A2= 10 , B2 = 35 and C2 = -50


Therefore,


A1/A2= 2/10 , B1/B2 = 7/35 = 1/5 and C1/C2 = -11/-50 = 11/50


Clearly,


A1/A2= B1/B2 not equal C1/C2


1/5 = 1/5 not equal 11/50

The given pair of equations has a unique solution. It is consistent.
