    so what are you going to do? I think the R2 will be R2/3

    yeah i was thinking that too. i'm having a hard time getting the 2nd, 3rd, 5th and 6th blanks.

    i really don't like it ... first it makes R1 zero, then R3 zero and then make R2 = 1 It it had asked to make R2 = 1 first ... then R1 = R1 - 2R2 and R3 = R3 + 4R3

    if ... R2 is not make 1 first then, your answer should be R1 = R1 - 2/3 R2 R3 = R3 + 4/3 R2
