Answer 2

To solve the given equation:

-0.4(3x-1) + 8(0.8 x 0.3) = 5 - (3.8x + 4)

Let's simplify the equation step by step:

-0.4(3x - 1) + 8(0.8 x 0.3) = 5 - (3.8x + 4)

First, let's simplify the expressions inside the parentheses:

-0.4 * 3x + 0.4 * 1 + 8 * (0.24) = 5 - (3.8x + 4)

Next, let's simplify the multiplications:

-1.2x + 0.4 + 1.92 = 5 - (3.8x + 4)

Combine like terms on both sides of the equation:

-1.2x + 2.32 = 5 - 3.8x - 4

Now, let's simplify the constants on the right side:

-1.2x + 2.32 = -3.8x + 1

Move all terms with x to one side of the equation:

-1.2x + 3.8x = 1 - 2.32

Combine like terms:

2.6x = -1.32

Finally, divide both sides by 2.6 to solve for x:

x = -1.32 / 2.6

After performing the division, the value of x is approximately -0.5077.
