X = 0.811

Explanation: To solve for X, you need to isolate X on one side of the equation. To do this, subtract 2.8 from both sides of the equation. This will leave you with x/3.1 = -0.091. Then, multiply both sides of the equation by 3.1 to get x = -0.811. Since the answer must be positive, the answer is 0.811.
