Subtract 5.3 from both sides, resulting in 2.8x = 7.4. Then, divide both sides by 2.8, resulting in x = 2.643 (when rounded to 3 decimal places).

Explanation:

To solve for x, you must isolate the variable. In order to do this, you must subtract the 5.3 from both sides of the equation. Next, you must get x alone by dividing by the coefficient 2.8. This results in an answer of x = 2.643.
