To find the number of solutions for this system of equations, we can solve these equations simultaneously.
We have the first equation, y=5x+7.
Substituting this value of y into the second equation, we get:
3(5x+7) - 15x = 18
15x + 21 - 15x = 18
21 = 18
This equation is not true, which means there is no solution for this system of equations.
Therefore, the system of equations has 0 solutions.
How many solutions does this system of equations have?
y=5x+7 and 3y-15x=18
