SUDOKU killer with inequalities - need help

Postby sudoker123 » Tue Aug 26, 2014 12:33 pm

hi, i am clueless, how to solve this killer sudoku with inequalities... so far i just know that 7th digit in 1st row is 7 (so 7th digit in 2nd row will be 8 or 9) and that i can divide the lower 19 cage into two smaller cages of sums 5 and 14... that is all i know, will appreciate any help, thanks in advance...

    the inequalities solve the 1 for c6
      r2c6 = 1
    -- follow immediately with the 1s for c1 and for r3
      r7c1 = 1
      r3c9 = 1
