she ment the answers to be 8-x=12

Answer 1

To solve the equation 8 - x = 12, you need to isolate the variable, "x," on one side of the equation.

Here's the step-by-step process:

1. Start with the equation: 8 - x = 12.

2. To isolate "x," you need to move the constant term, "8," to the other side of the equation. You can do that by subtracting 8 from both sides:

8 - x - 8 = 12 - 8

Simplifying, you get:

-x = 4

3. Since "-x" means the negative of "x," you can multiply both sides of the equation by -1 to get rid of the negative sign:

-1 * -x = -1 * 4

Simplifying further:

x = -4

Therefore, the solution to the equation 8 - x = 12 is x = -4.
