Answer: 3z + 2z = 50
Step-by-step explanation: To eliminate the fractions in the equation z/2 + z/3 = 25/3, you need to find a common denominator for the fractions. The least common multiple (LCM) of 2 and 3 is 6. So you can multiply both sides of the equation by 6 to get rid of the denominators. This gives you 3z + 2z = 50.
