Answer 2

To solve the equation, you'll need to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the constants on both sides of the equation to the terms inside the parentheses:

   -1.2(x + 3) + 2.9 = 4.5 - 0.6(-x - 0.3)

   Now, simplify both sides of the equation:

   -1.2x - 3.6 + 2.9 = 4.5 + 0.6x + 0.18

2. Combine like terms on each side of the equation:

   -1.2x - 3.6 + 2.9 = 4.5 + 0.6x + 0.18

   -1.2x - 0.7 = 4.68 + 0.6x

3. Move the terms involving x to one side of the equation by adding 1.2x to both sides:

   -1.2x + 1.2x - 0.7 = 4.68 + 0.6x + 1.2x

   -0.7 = 4.68 + 1.8x

4. Next, subtract 4.68 from both sides of the equation to isolate the terms with x on the right side:

   -0.7 - 4.68 = 4.68 - 4.68 + 1.8x

   -5.38 = 1.8x

5. Finally, divide both sides by 1.8 to solve for x:

   (-5.38) / 1.8 = (1.8x) / 1.8

   -2.9889... ≈ x

So, the solution to the equation is approximately x ≈ -2.9889... or you can round it to x ≈ -2.99 (rounded to two decimal places).
