To solve the first equation, 8 + 3b = -7 + 2b, you would first combine like terms by subtracting 2b from both sides:

8 + b = -7

Next, subtract 8 from both sides:

b = -15

Therefore, the solution to the first equation is b = -15.

To solve the second equation, -3d - 10 = 3d - 6, you would first add 3d to both sides:

-3d - 10 + 3d = -6

Combine like terms:

-10 = -6

However, since this equation is not true, there is no solution for this equation.
