k + 6k - 13 = 177k = 30k = 30/7k = 4.2857
-47 + 6k = 3k - 2Add 47 to each side:6k = 3k +45Subtract 3k from each side:3k = 45Divide each side by 3:k = 15
6k + 21 = 36k + 21 - 21 = 3 - 216k = -186k/6 = -18/6k = -3A check to make sure this is right:6(-3) + 21 = 3-18 + 21 = 33 = 3Yes, this is correct.
72 + 72 = 144
Same as subtracting 6 from 7 = K
8k = 6k - 26 8k - 6k = 6k - 6k - 26 2k = -26 2k / 2 = -26 / 2 k = -13. The answer is k = -13.
11 + 6k = 65 Subtract 11 from both sides: 6k = 65-11 6k = 54 Divide by 6 to get k: k = 54/6 k = 9
k + 6k - 13 = 177k = 30k = 30/7k = 4.2857

No, it equals .017077 4216 divided by 72 equals 58.55
Same as subtracting 6 from 7 = K
72.
You would formulate this problem X/100 * 150 = 72 and solve for X.
