Answer 2

To solve the equation 0.3(2x - 1) - 0.9 = 0.2(5x - 2), follow these steps:

1. Distribute the constants on the left side and right side of the equation:

   0.6x - 0.3 - 0.9 = 1x - 0.4

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

   0.6x - 1.2 = 1x - 0.4

3. Move all the terms involving x to one side of the equation and the constants to the other side. You can do this by subtracting 1x from both sides and adding 1.2 to both sides:

   0.6x - 1x = -0.4 + 1.2

4. Simplify the equation:

   -0.4x = 0.8

5. Finally, solve for x by dividing both sides by -0.4:

   x = 0.8 / -0.4

Now, calculate the value of x:

x = -2

So, the solution to the equation is x = -2.
