The video tutorial demonstrates how to solve for x in the equation Y = 2/3x - 12. The instructor introduces the concept of pinning the variable and using inverse operations to simplify the equation. By adding 12 to both sides and multiplying by the reciprocal of 2/3, the equation is solved step-by-step. The tutorial emphasizes careful handling of fractions and concludes with the final solution.
