Answer 3

Solving the Equation 2x - 4.2 = 6.8

To solve the equation 2x - 4.2 = 6.8, we can follow these steps:

1. Add 4.2 to both sides of the equation: - 2x - 4.2 + 4.2 = 6.8 + 4.2 - 2x = 11

2. Divide both sides by 2: - 2x / 2 = 11 / 2 - x = 5.5

Therefore, the solution to the equation 2x - 4.2 = 6.8 is x = 5.5.
