4.5

Step-by-step explanation:

  1. solve both the SIDES of the equation
  2. on solving you would get a quadratic equation
  3. PUT the NUMERIC part ( the part of the equation without VARIABLE) on RHS
  4. you would get the following equation :

2x^3 - 27x^2 + 123x = 189

5. put the given values i.e. 2.6, 4.5, 3.8, 6.1 in the equation to check whether it satisfies the equation or not

6. on putting the values you will FIND that the answer is 4.5
