Answer 2

To solve the equation 2(11x - 5) - 17x = 55 + 5(8x + 3) - 12 = 83, we will simplify and solve step by step.

Let's simplify the equation step by step:

1. Distribute the multiplication: 22x - 10 - 17x = 55 + 40x + 15 - 12 = 83

2. Combine like terms: (22x - 17x) - 10 = 55 + (40x + 15) - 12 = 83 5x - 10 = 40x + 58

3. Move all terms involving x to one side and constant terms to the other side: 5x - 40x = 58 + 10 -35x = 68

4. Divide both sides by -35 to solve for x: x = 68 / -35 x ≈ -1.942857143

So the solution to the equation 2(11x - 5) - 17x = 55 + 5(8x + 3) - 12 = 83 is x ≈ -1.942857143.
