Question

write a pair of line which has unique solution x=-1,y=3​

Answer 1

Step-by-step explanation:

The required equations are 2x+3y= 72x+3y=7 and 5x+2y= 15x+2y=1

Step-by-step explanation:

Given : A pair of linear equations which has the unique solution x= -1, y=3.

To find : How many such pairs can u write?

Solution :

• Now, We have to make up a pair of linear equations with solution: x=-1 and y =3.

Let, 2x = -22x=−2 and 3y = 93y=9

1st Equation form is 2x+3y= 72x+3y=7

Let, 5x = -55x=−5 and 2y = 62y=6

2nd Equation form is 5x+2y= 15x+2y=1

Therefore, The required equations are 2x+3y= 72x+3y=7 and 5x+2y= 15x+2y=1

Answer 2

a pair of line which has unique solition means that lines are intersecting at a point.

ax+by+c=0

put x=1,y=3 in eqn

x+3b+c=0 hence infinite lines can be intersect at tgis point
