Answer 2

Answer:

In each of the following systems of equation determine whether the system has a unique solution, no solution or infinite solutions. In case there is a unique solution,

x − 3y − 3 = 0, x − 3y − 3 = 0

3x − 9y − 2 = 0, 3x − 9y − 2 = 0

Solution:

The given system may be written as

x − 3y − 3 = 0

3x − 9y − 2 = 0

The given system of equation is of the form

a2x + b2y − c2 = 0 a2x + b2y − c2 = 0

Where, a1 = 1, b1 = −3, c1 = −3

a2 = 3, b2 = −9, c2 = −2

We have,
