Answer 3

Let's solve the given equation step by step:

1. Distribute the terms on the left side: 7(x - 1) - 3(2x + 1) = 7x - 7 - 6x - 3

2. Combine like terms: 7x - 7 - 6x - 3 = (7x - 6x) + (-7 - 3) = x - 10

3. Now, the equation becomes: x - 10 = -x - 15

4. Get all the x terms on one side and constants on the other side: Move -x from the right side to the left side by adding x to both sides: x - x - 10 = -x + x - 15

Simplify: -10 = -15

5. The equation simplifies to -10 = -15, which is not a true statement. This means that there is no solution to the given equation. In other words, the equation has no value of x that makes it true.
