Question

find whether the linear equation 4x-2y-1=0 has a unique solution or not

Answer 1

Hi ,

Every linear equation in two

variables has infinitely many

solutions .

ax + by + c = 0 has infinitely many

solutions.

Therefore ,

4x - 2y - 1 = 0 has infinitely many

solutions

I hope this helps you.

:)

Answer 2

4x-2y-1=0.
y = (4x-1)/2.
for x=1,we have y=3/2.
for x= 2,we have y=7/3.
and so on.
from the above conclusion we can conclude that the equation 4x-2y-1=0 has many solutions.
Therefore, 4x-2y-1=0 has no unique solution.
