Question

The pair of linear equations x 2y 5=0 and -3x-2y 1 =0 have :
A) unique solution B) exactly 2 solutions C) infinitely many solution
D) no solution VERY VERY URGENT PLZZ .......

Answer 1

Answer:

c is the corret answer of the question

Answer 2

option (d)

The pair of linear equations has no solution

Step-by-step explanation:

given equations are

x+2y+5=0

-3x-6y+1=0

on comparing with $a_1x+b_1y+c_1=0 , a_2x+b_2y +c_2=0$

we have

$a_1 = 1, b_1=2,c_1=5\\\\\a_2=-3,b_2-6,c_2=1$

here ,

$\frac{a_1}{a_2}= \frac{-1}{3}, \frac{b_1}{b_2}= \frac{-2}{6}= \frac{-1}{3}\\\\\frac{c_1}{c_2}= \frac{5}{1}\\\\\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq \frac{c_1}{c_2}$

therefore , The pair of linear equations has no solution
