work.

To solve the equation -15 = 12 - 8 using substitution, we first need to simplify the right side of the equation:

12 - 8 = 4

Now, we substitute this value back into the equation:

-15 = 4

This equation is not true, so both Mikayla and Jesse are incorrect in their solutions. The correct answer is that there is no solution to this equation, as the left side does not equal the right side.
