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).


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.
