The answer is - 100k + 3 + 101k = - 245 - 181k. In the equation - k + 0.03 + 1.01k = - 2.45 - 1.81k, numbers have two decimals. So, if we multiply both of sides by 100, we will get whole numbers: 100 (-k + 0.03 + 1.01k) = 100 (-2.45 - 1.81k). 100 * (-k) + 100 * 0.03 + 100 * 1.01k = 100 * (-2.45) + 100 * (-1.81k). - 100k + 3 + 101k = - 245 - 181k.
