Answer:

B = -2

Explanation:

To solve the equation -9+7b=8b-7, you want to isolate the variable (b) on one side of the equation. Here are the steps to do that:

1. Start by simplifying both sides of the equation. Add 9 to both sides to eliminate the -9 on the left side:

-9 + 7b + 9 = 8b - 7 + 9

Simplifying this, we get:

7b = 8b + 2

2. Now, we want to isolate the variable (b) on one side of the equation. We can do this by subtracting 8b from both sides:

7b - 8b = 8b + 2 - 8b

Simplifying this, we get:

-b = 2

3. To solve for b, we need to isolate it by itself. We can do this by multiplying both sides by -1:

-b(-1) = 2(-1)

Simplifying this, we get:

b = -2

So the solution to the equation -9+7b=8b-7 is b = -2.
