does this have a solution

2007-06-26 07:24:49 · 6 answers · asked by christianoi2039 2

my question is this. the problem is 4x -12y = 5 and -x + 3y = -1.

In order to do this i have to switch the problem so its y = or x =. well the second problem x is negative. do i multiply the problem by negative one so that x is positive?
