  • intermediate algebra -

    multiply first equation by 2
    -30r+24s=48
    +30r-24s=48
    hmm, if I add those, I get 0 = 96. a problem all right
    try multiplying the second one by -1 then look
    -30r+24s=48
    -30r+24s=-48

    that is two parallel lines with the same slope but they never cross (different intercepts). There are no solutions.
