Answer 3

To solve the equation 2(5 - x) - 7 = -6x - 1, we will follow these steps:

1. Distribute the 2 to the terms inside the parentheses: 10 - 2x - 7 = -6x - 1.

2. Combine like terms on both sides of the equation: 3 - 2x = -6x - 1.

3. Add 6x to both sides to isolate the variable terms on one side of the equation: 6x + 3 - 2x = -1.

   Simplifying the left side gives: 4x + 3 = -1.

4. Subtract 3 from both sides: 4x = -1 - 3.

   Simplifying the right side gives: 4x = -4.

5. Divide both sides of the equation by 4 to solve for x: x = -4 / 4.

   Simplifying the right side gives: x = -1.

Therefore, the solution to the equation 2(5 - x) - 7 = -6x - 1 is x = -1.
