Answer:
To isolate the variable "v" in the equation 8 = 7 - v, you can follow these steps:
1. Start with the original equation:
8 = 7 - v
2. Subtract 7 from both sides of the equation to isolate the term with "v" on the right side:
8 - 7 = -v
3. Simplify the left side of the equation:
1 = -v
4. Finally, to solve for "v," multiply both sides of the equation by -1 to get "v" by itself:
-1 * 1 = -1 * (-v)
This results in:
-1 = v
So, the equation 8 = 7 - v is equal to v = -1.
