Answer:

The system has infinite solutions

Explanation:

For a system of two linear equations it is always true that if one equation is a linear combination of another, then the system will have infinite solutions.

Suppose we have the following system:


ax + by = c\\dx + hy = f

If there is a number n for which it is fulfilled that


<a, b, c> = n * <d, h, f>

Then the system has infinite solutions.

In this case the system is:


x + 2y=10\\3x+6y =30

Observe that:


<1, 2, 10> = (1)/(3)* <3, 6, 30>

Then
n =(1)/(3)

The system has infinite solutions
