Question

Write the pair of linear equations which has a unique solution x=1 and y=2​

Answer 1

$\huge\boxed{\underline{\underline{\green{Solution}}}} </p><p>$

$\displaystyle \: \longmapsto \: \:$FORMULA TO BE IMPLEMENTED :

A pair of Straight Lines

$\displaystyle \: a_1x+b_1y+c_1=0 \: and \: \: a_2x+b_2y+c_2=0$

Is said to be consistent Unique Solution) if $\displaystyle \: \: \frac{a_1}{a_2} \ne \frac{b_1}{b_2}$

$\displaystyle \: \longmapsto \: \:$CALCULATION :

So by the above formula we can say that

There are many pair of linear equations whose Solutions are x = 1, y = 2

One of such pair of linear equations are

x + 2y = 5

2x + y = 4

Answer 2

Answer:

x + y = 5 , 2x+ y= 4..
