8. 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. 2x + 4(-5y + 1) = -4

C. 2x + 4(5y - 1) = -4

D. 2(5y - 1) + 4y = -4
