Answer 2

To solve the equation for x, you need to combine like terms and isolate x. Here's how you can do it step by step:

1. Combine like terms on the left side of the equation: 2x + 3x + 4.2 = 21.2

   Combine the x terms: 5x + 4.2 = 21.2

2. Next, subtract 4.2 from both sides of the equation to isolate the variable x: 5x + 4.2 - 4.2 = 21.2 - 4.2

   This simplifies to: 5x = 17

3. Finally, divide both sides by 5 to solve for x: 5x / 5 = 17 / 5

   x = 17 / 5

So, the solution to the equation is: x = 17/5 or x = 3.4
