A beetle is down in the ground and he digs down to find an ant. A beetle starts at 2 inches below ground level. The beetle digs down of the distance, d, that the ant is below ground level. The beetle is now at 4 inches below ground level. What is the distance, d, the ant is below ground level? Write an equation that best represents how to find the distance that the ant is below ground level.

Solve the equation from Part (a). Show your work. What is the distance, d, that the ant is below ground level?
