If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.

15x – y = –6
5x – 3y = –13

5(–15x – 6) – 3y = –13
5x – 3(15x + 6) = –13
5(15x + 6) – 3y = –13
5x – 3(–15x – 6) = –13
