Answer :

The given linear equations are infinite number of solution.

Step-by-step explanation:

The given linear equations are:

6x + 45y = 192                         ........... (1)

and - 4x - 30y = - 120              ........... (2)

To find, the number of solutions = ?

Multiplying (1) by 1.5, we get

1.5(- 4x - 30y) = 1.5(- 120)  

- 6x - 45y = - 180                    ........... (3)

Adding equations (1) and (3), we get

6x + 45y - 6x - 45y = 192   - 180    

0 = - 12

Thus, the given linear equations are infinite number of solution.
