Answer 2

It looks like you've provided an equation, and it seems to involve some calculations. To assist you, I'll break down the equation and solve it step by step:

The equation you've given is:

4x - 5(4x - 5) + 8.5x = 0.3(3x - 7) + (2x - 15.6) / 7

Let's solve it step by step:

1. Distribute the constants and variables within the parentheses:

   4x - 20x + 25 + 8.5x = 0.3 * 3x - 0.3 * 7 + (2x - 15.6) / 7

2. Combine like terms on both sides of the equation:

   -7.5x + 25 = 0.9x - 2.1 + (2x - 15.6) / 7

3. Move the terms involving 'x' to one side and the constants to the other side:

   -7.5x - 0.9x - (2x - 15.6) / 7 = -2.1 - 25

4. Combine the terms on the left side of the equation:

   -8.4x - (2x - 15.6) / 7 = -27.1

5. Multiply both sides of the equation by 7 to eliminate the fraction:

   -58.8x - 2x + 15.6 = -189.7

6. Combine the 'x' terms on the left side:

   -60.8x + 15.6 = -189.7

7. Subtract 15.6 from both sides:

   -60.8x = -205.3

8. Finally, divide both sides by -60.8 to solve for 'x':

   x = -205.3 / -60.8 x ≈ 3.377

So, the solution for the equation is approximately x = 3.377.
