Answer 2

To solve the equation 1.4x(3 + 5x) = 2x(3.5x - 2) - 4.1, follow these steps:

1. Distribute on both sides of the equation to simplify it:

   1.4x(3) + 1.4x(5x) = 2x(3.5x) - 2x(2) - 4.1

2. Now, perform the multiplications:

   4.2x + 7x^2 = 7x^2 - 4x - 4.1

3. Next, move all the terms to one side of the equation:

   4.2x + 7x^2 - 7x^2 + 4x + 4.1 = 0

4. Simplify the equation further:

   8.2x + 4.1 = 0

5. Subtract 4.1 from both sides:

   8.2x = -4.1

6. Finally, divide both sides by 8.2 to solve for x:

   x = -4.1 / 8.2

   x = -0.5

So, the solution to the equation is x = -0.5.
