Using order of operations, you have\n19 - 13/(5)(3) - 15\n= 19 - 39/5 - 15\n= 4 - 39/5\n= 20/5 - 39/5 \n= -19/5\n= -3.8

Add the K together\n-5K-13K= -18K then add the numbers -19+5= -14\n-18K - 14 =0\nadd 14 to each side\n-18K = 14\nDivide both sides by -18\n-18K/-18 = 14/-18\nK= -14/18  then reduce the fraction K= -7/9

your question has a problem...............\nif the sum is 13, then the other number has to be -35, which will not meet your other condition

Just "pair up" the terms.\n\n1 + (5-3) + (9-7) + (13-11) + ... + (2001-1999)\n\n1 + 2 + 2 + 2 + .... + 2 = 1 + 2 * 500 = 1001
