3x - 2y = -3 6x - 5y = -9 is awkward.   write this system as3x - 2y = -3 6x - 5y = -9there, right in front of you, are the coefficients that make up the matrix equation you want.   the first row is     3   -2   = -3what is the second row? , ask questions about tough math problems before you take the test, not during.
