For this case we have the following system of equations:
 1/3 y - 5 = 2x
 y = 15 + 6x
 The equations are linearly dependent, that is, there is a scalar that allows us to write an equation as a linear combination of the other.
 We multiply the equation (1) by a scalar, which will be 3:
 3 * (1/3 y - 5) = 3 * (2x)
 Rewriting:
 y-15 = 6x
 y = 15 + 6x
 Answer:
 
Therefore, if there is a solution, then there are infinite solutions.
