Example 1 showed how to write both sides of an exponential equation with a common base. After this step is complete, you are left with a basic equation that can be solved for the unknown variable. Example 2 demonstrates this.
When the solution x = -1 is substituted into the original equation, the left side of the equation equals the right side of the equation. This means x = -1 is verified to be correct. |
