There are 0 solutions.
1) Bring the 2 equations to standard form:
y-5x = -6 => y=5x-6
3y-15x = -12 => y=5x-4
2) Looking at the standard equitation, we see by the slope of the 2 equations (5x) that the 2 equations are parallel, and therefore never intersects.
(When they ask for solutions, it's asking for how many times the equations intersect.)
