Answer 1

To solve the equation 2-7=-9, we need to isolate the variable. However, there is no solution to this equation.

Step-by-step explanation:

The given equation is 2 - 7 = -9. To find the solution, we need to isolate the variable, which in this case is the unknown number.

First, let's simplify the left hand side of the equation by subtracting 7 from 2: 2 - 7 = -5.

Now, the equation is -5 = -9. Since -5 is not equal to -9, there is no solution to this equation. Therefore, none of the number lines represents the solution to the equation.
