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.

Substitution method is super easy. :) 

Since it said find the equivalent to y in the first equation...

you need to isolate y! 

-y = -6x + 1
y = 6x - 1

Now that you have your equation, just substitute that into the second equation. 

4x -3(6x - 1) = -11
4x - 18x + 3 = -11

-14x + 3 = -11
-14x = -14

now divide

x = 1

YOUR answer however would be y = 6x - 1

this is what was under the question but not part of the answers     
 8x - y = -9 
4x - 3y = -22

4(-8x - 9) - 3y = -22                                                                                    4x - 3(-8x - 9) = -22                                                                                       4(8x + 9) - 3y = -22                                                                                         4x - 3(8x + 9) = -22  these are the choices
