Answer 2

It seems like you have an equation that you'd like to solve for the variable "x." Let's solve it step by step:

1. Start with the equation: 20 - 2.5x = 3.5x - 14

2. To isolate the variable "x" on one side of the equation, we can first add 2.5x to both sides of the equation to move the variable terms to one side:

   20 - 2.5x + 2.5x = 3.5x - 14 + 2.5x

3. This simplifies to:

   20 = 6x - 14

4. Next, add 14 to both sides to isolate the term with "x" on one side:

   20 + 14 = 6x - 14 + 14

5. This simplifies to:

   34 = 6x

6. Finally, divide both sides by 6 to solve for "x":

   34 / 6 = 6x / 6

7. The solution is:

   x = 34 / 6

8. Simplify the fraction:

   x = 17 / 3

So, the value of "x" is 17/3, which is equivalent to 5.67 when rounded to two decimal places.
