Kylie wants to solve the given system of linear equations. 3x + 2y = 13 x - 4y = 9 Her method is to replace the second equation with an equivalent form so that she can eliminate one of the variables by adding the equations together. Kylie rewrites the system of equations as follows: 3x + 2y = 13 -3x + 12y = What number should go in the blank space to produce the same solution as the original system?
