If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.
x – 6y = –15
x – 3y = –3

x – 3(6y – 15) = –3

x – 3(–6y – 15) = –3

(6y – 15) – 3y = –3

(–6y – 15) – 3y = –3
