Answer 3

To solve the equation 0.6(2x - 3) = 0.4(9 + 3x) - 2(x - 0.9), you can follow these steps:

1. Distribute the values inside the parentheses:

   0.6 * 2x - 0.6 * 3 = 0.4 * 9 + 0.4 * 3x - 2 * x + 2 * 0.9

2. Simplify each side of the equation:

   1.2x - 1.8 = 3.6 + 1.2x - 2x + 1.8

3. You can see that you have "1.2x" and "-1.2x" on both sides of the equation, which will cancel out.

   -1.8 = 3.6 - 2x + 1.8

4. Now, let's isolate the "2x" term by moving the constants to the other side of the equation:

   -1.8 - 3.6 + 1.8 = -2x

5. Simplify the constants on the left side:

   -3.6 = -2x

6. Now, divide both sides by -2 to solve for "x":

   x = (-3.6) / (-2)

7. Finally, calculate the value of "x":

   x = 1.8

So, the solution to the equation is x = 1.8.
