This is a linear system of equations.
The first equation y = 5x + 7 represents a line with a slope of 5 and a y-intercept of 7.
The second equation 3y - 15x = 18 can be simplified to y - 5x = 6, which represents another line with the same slope of 5.
Since both equations represent lines with the same slope but different y-intercepts, they will intersect at a single point, indicating that this system of equations has one solution.
Match the system of equations to the number of solutions it has.
