In the first equation, solve for one of the variables in terms of the others. Substitute this expression into the remaining equations. This yields a system of equations with one fewer equation and one fewer unknown. Repeat until the system is reduced to a single linear equation.

Mammoth Cave, in Kentucky, a horizontal cave, is the longest cave system in the world, stretching for at least 390 miles (627 kilometers) beneath the surface of the Earth. However, some caves turn this tidy formula on its head and form from the bottom up. Water trapped in aquifers deep inside the Earth sometimes comes into contact with sulfide-loaded rocks, like pyrite, Orndorff said. This creates sulfuric acid, which, with enough hydraulic pressure, can push up through the rock to carve out a cave.
