Answer 2

To solve the equation 1.15 + 0.85(36.02 - 0.8x) = 26.99, you'll need to follow these steps:

1. Start by distributing the 0.85 on the left side of the equation:

   1.15 + 0.85 * 36.02 - 0.85 * 0.8x = 26.99

2. Next, perform the multiplications:

   1.15 + 30.617 - 0.68x = 26.99

3. Now, subtract 30.617 from both sides of the equation to isolate the term with 'x' on the left side:

   1.15 - 30.617 - 0.68x = 26.99 - 30.617

4. Simplify the equation:

   -29.467 - 0.68x = -3.627

5. To solve for 'x', you'll want to isolate 'x' on the left side. First, add 29.467 to both sides of the equation:

   -0.68x = -3.627 + 29.467

6. Simplify further:

   -0.68x = 25.84

7. Finally, divide by -0.68 to find the value of 'x':

   x = 25.84 / -0.68

8. Calculate the result:

   x ≈ -37.94

So, the solution to the equation is approximately x ≈ -37.94.
