Show that the system of equations2x+5y=17‚5x+3y=14Has a unique solution .find the solution

Answer»

Answer:

2x+5y-17=0,5x+3y-14=0

here a1=2,b1=5,C1= -17

a2=5,b2=3,C2= -14

\frac{a1}{a2}  not \: equal \frac{b1}{b2}  \\ so \: this \: lines \: have \: unique \: solution \\ since \: these \: are \: interesting \: lines
