I believe you are referring to this equation: (9u-11)/2 = (19u +11)/3. To solve this step-by-step, first, multiply each side by 6 which is the least common denominator of 2 and 3. This then results to: 27u - 33 = 38u + 22. Second, combine like terms on one side such that: 11u = -55. Finally, the value for u is calculated to be -5.
