Answer 2

Let's solve the given equation step by step:

1. Simplify the expressions on both sides of the equation:

8*(3.7 - x) + (1.2 - 5x) = 5*(4 - 3x) + 8x = (-3.2 - 4.3) / 2.5 + (1.8 - 4) - 1.1

2. Perform the operations inside the parentheses:

8*(3.7 - x) + (1.2 - 5x) = 5*(4 - 3x) + 8x = (-7.5) / 2.5 + (-2.2) - 1.1

3. Simplify the expressions further:

8*(3.7 - x) + (1.2 - 5x) = 5*(4 - 3x) + 8x = -3 - 2.2 - 1.1

4. Combine like terms:

29.6 - 8x + 1.2 - 5x = 20 - 15x + 8x = -6.3

5. Rearrange the equation to isolate the variable:

-13x + 30.8 = -6.3

6. Move the constant term to the other side:

-13x = -6.3 - 30.8

7. Combine the constant terms:

-13x = -37.1

8. Divide both sides by -13 to solve for x:

x = -37.1 / -13

9. Calculate the value of x:

x ≈ 2.8538

So, the approximate value of x that satisfies the given equation is x ≈ 2.8538.
