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 + 5y = 1. 2x + 4y = –4. a. 2(5y – 1) + 4y = –4. b. 2(–5y + 1) + 4y = –4. c. 2x + 4(–5y + 1) = –4. d. 2x + 4(5y – 1) = –4
